KYC: The Process, the Layers and What e-KYC Changed
Know-your-customer (KYC) is the check an arrangement runs before it will open an account. The check establishes two facts, who somebody is and where they can be reached, against evidence the arrangement will accept, and it keeps a record that the check happened. A threshold is all it is, and not a judgement. The electronic route changed how those facts may be established and left what must be established exactly where it was.
An arrangement that holds money for somebody has to be able to attribute the account to somebody, and it has to be able to answer for that account when an authority asks. Neither is possible if it does not know whose account it is. So before it will begin, it establishes two facts and files a record that it did so. Four questions unpack that single sentence: which facts, what evidence establishes them, how that evidence reaches the arrangement, and how long the filed record stays good. All four answers are sentences somebody wrote down, and not one of them is a measurement of anybody.
What is know-your-customer actually for?
The answer lives on the arrangement's side, so ask the question from there. There are two reasons and the second one is the one everybody quotes, so start with the first. An arrangement that cannot attribute an account to somebody cannot return the money in it, cannot act on an instruction about it, and cannot answer a question about it. Every ordinary service a deposit account provides depends on the arrangement being able to say whose it is and where to reach that person. Take that away and the account is not a lighter version of an account, it is an unusable one.
The second reason is the one that gets stated: an authority requires the check, and requires a record that the check was done. The requirement to run the check and to keep the record is real, and it binds. But an account that gives only the second reason leaves a reader thinking the whole thing is paperwork imposed from outside, and it is not. The paperwork sits on top of a working requirement the arrangement would have anyway.
The check is not an assessment of anybody. It produces no score, no rating, no opinion and no ranking. Completing it says exactly one thing: two facts were established against evidence the arrangement accepts. Not completing it says exactly one thing too, set out below, and that one is not about a person either. A locker room that will not hand over a key until it can attribute the locker to somebody is protecting whatever is inside the locker, and the rule is a fact about the locker room. Nobody standing at the desk has been evaluated.
What are the three layers of the check, and which one is which?
Almost every confused argument about this subject comes from treating one thing as three, or three things as one. Separating them once, properly, settles most of those arguments before they start.
Layer one is what must be established: who somebody is, and where they can be reached. Layer two is how it may be established: which evidence the arrangement will accept, and in what form that evidence may arrive. Layer three is how often it is done again. A record established once does not stay established forever, so the arrangement runs a periodic reviewGoing back over a fact that was already established, at set intervals rather than once, so that a record filed some time ago is confirmed as still current. at intervals and sooner if something about the account changes.
The first layer has barely moved in decades and the second has been rebuilt, and almost every argument about this subject is really an argument about the second layer wearing the first layer's name. When somebody says the requirement got easier, listen for which layer they mean. If the same two facts still have to be established, layer one did not move at all. The evidence route moved. The two layers have different owners, change at different speeds, and fail in completely different ways, so the distinction is neither small nor pedantic.
The contents of all three layers belong to the Reserve Bank of India, and they change when it changes them. A list of accepted evidence changes when the Reserve Bank of India changes it. A list that was right two years ago gets carried away and acted on, and that makes it worse than no list at all.
Which of the three layers just separated did the electronic route change?
A check runs, and finds no record anywhere to compare the details against. Which of the three answers does the comparison return?
What can a check confirm, and what can it never confirm?
Here is the mechanism, and it is sharper than the word check suggests. A check does not investigate anything. It compares. Something presented is set against something already recorded, and the comparison returns one of exactly three things: a match, a mismatch, or nothing at all. The third return, nothing at all, carries the whole argument, and it repays slow reading.
Readers move past the consequence at speed, so it is worth stating slowly. A check can only ever confirm a fact that was recorded somewhere, by somebody, at some point. Where no record of the fact exists, the comparison has nothing to sit the details against, so it returns nothing rather than returning a wrong answer. The check has not failed. The check has reported, accurately, that this registerSomewhere a fact was set down and kept so that it can be looked up later. A list of who lives at which address is one. So is a list of births. holds nothing to compare against.
So here is the line: a missing record is a gap in a register. The gap is a fact about what somebody once wrote down and filed, and about the completeness of a filing system. The gap is not a fact about the person the record is missing for. A library catalogue with no entry for a book says something about the catalogue. Whether the book exists is a separate question the catalogue was never able to answer, and reading the empty line as evidence about the book is a mistake in reading, not a discovery.
A register holds no entry at all for an address. An absence like that is a property of which thing?
What are the routes by which the same fact gets established?
There are three, named here by function only. Route one is in person against something presented: a document is carried to a counter, looked at there, and a copy is kept. Route two is electronically against a record already held: the details presented are compared against a record kept elsewhere, and the comparison returns its answer without anything physically travelling. Route three is by relianceOne arrangement accepting a check that a different arrangement already completed, instead of running the same comparison again from the start.: an arrangement uses a check already completed somewhere else rather than repeating it.
All three establish the same fact, and they differ only in what has to travel, how far it goes, and how long it takes. The comparison between the three routes ends there. Nothing about who somebody is changes depending on which of the three routes established it, and no route produces a stronger or weaker version of the fact. Logistics is all that differs, and logistics is where the cost lives.
Names are the least durable thing about any of these routes. Names change, the arrangements sitting behind the names change, and a treatment written around a name goes wrong in a way one written around a function does not. Function survives the rename. A reader who has understood route two understands every future version of route two, whatever anybody calls it next.
Name what actually differs between establishing a fact at a counter and establishing the same fact electronically.
Move the route and move the register, and watch what the comparison returns
Two things move on the control below: the route the evidence takes, and the state of the filing it is compared against. Both are properties of arrangements rather than of people. The top band never changes at any setting, because what must be established is the same at every one of the twelve settings.
On the electronic route, the details presented are compared against a record already held, so nothing physically travels and the comparison takes as long as the comparison takes. The register holds a record and the record agrees with the details, so the comparison returns a match, and what has been established is that the two agree with each other.
Educational illustration. Twelve settings, and every one of them turns on the route and the register rather than on any person. Which evidence an arrangement may accept is set by the Reserve Bank of India and moves. Route three is one arrangement using a check another has already completed, and neither of the two is named.
Two features of that control are worth noting. First, set the register to hold no record and move the route across all three positions. A route decides what travels and never decides what was filed, so the return stays at nothing at all on every one of them. No amount of improvement to the second layer creates a record that nobody ever wrote down. Second, set the register back to holding a record. Layer one is not on the control at all, so the top band stays put at every setting while everything else moves.
What did the electronic route change, and what did it leave exactly where it was?
The electronic route changed the second layer and not the first. Everything below is detail underneath that one line. The same two facts still have to be established. The record that the check happened is still kept. The change is in what has to travel: instead of a document and a journey to a counter inside that counter's opening hours, a comparison runs against a record already held.
Three things moved when that happened, and each of them is one of the barriers a counter puts in the way. The distance stopped being a journey. The time stopped being a queue and an appointment inside somebody else's opening hours. And the cost of delivery stopped being a counter's fixed cost divided by the uses passing through it. Dividing that fixed cost by those uses is the arithmetic that decides whether a point of serviceAnywhere a financial service can be reached from at all: a counter, a machine, an agent, an application. Whether one exists in a given place turns on what it costs to run against how many uses go through it. exists at all in a thinly used location.
Now the counterweight. An account that stops after the good half is selling something. An electronic route works where a record exists to compare against, so it moves the threshold from a journey to a register. That is a genuine move and it is not a small one. But a move is not a removal. Where the register holds nothing, the route returns nothing, instantly and at no cost, and instant is faster without being an answer. The barrier changed shape from distance into filing.
And here is the limit of what the material supports. The material carries one arrangement, one year, and no second period at all. The effect of the electronic route on the cost and the distance is a statement about mechanism; what it achieved would be a statement about outcomes. One arrangement in one year cannot test the second claim, and a claim made anyway would be a conclusion dressed as a finding.
What does the check cost, and who carries that cost?
Start with the absence, out loud. The absence decides how far the cost question can be taken. The cost of running these checks at Suvarna Commercial Bank Limited, an invented bank, sits inside a single line: operating expensesEverything an institution spends to run itself for the year, added into one line: staff, premises, technology, and the running of every process it operates. Reported as one figure unless the institution chooses to break it up. of Rs 5,040 crore for the year. The material carries no split of that line at all. The share of that line the check accounts for cannot be stated. A made-up share gets carried away and repeated as though somebody had measured it, and no made-up share is offered in its place.
Without the split, the shape can still be said, and the shape is the part that generalises. The check is mostly a fixed cost per accountA cost that is the same for every account regardless of how much money is in it, because the work behind it does not get bigger when the balance does. rather than a cost that rises with the balance in the account. Running a comparison takes what it takes whether the account holds a little or a lot. So measured per rupee held, the same cost lands very differently across accounts, and it lands hardest on the smallest ones.
The shape of that curve is a property of arithmetic and of nothing else. A fixed cost sitting on a variable base always weighs most on the smallest base, in every business anywhere, and the curve above would look the same for the cost of issuing a receipt or the cost of posting a statement. The curve is a fact about the cost structure of the check. The curve is not a fact about anybody holding a small balance, and the arithmetic does not need one, so no person is drawn on it. The same arithmetic is the reason a lighter route exists at all: where the cost of the full check is heavy against a small base, an arrangement that wants to serve that base needs a cheaper way to cross the same threshold.
The conditions riding on an account opened under a lighter check, and what such an account may then do, belong to the Reserve Bank of India, and they change when it changes them. A row below carries the name of the body that fixes them and a blank where the answer would go. A blank against a named address is the honest shape for anything that moves.
A check costs the same to run whatever the balance in the account. Read per rupee held, where does that cost land hardest, and what kind of statement is that?
What can one bank's own figures say about the cost of a check?
Less than a reader would want, and saying so precisely is more useful than filling the gap. The material for Suvarna Commercial Bank Limited runs to one single year, and the period is named because both lines belong to the same one.
| What the material carries, for one year | Figure |
|---|---|
| Deposits, every rupee of which sits in an account behind a completed check | Rs 1,92,000 crore |
| Total income for the year | Rs 9,840 crore |
| Operating expenses for the year, as one undivided line | Rs 5,040 crore |
| Operating expenses over total income, which is the division printed rather than the answer quoted: Rs 5,040 crore over Rs 9,840 crore of total income | 51.22 per cent |
The last row of the table is the cost to income ratioWhat an institution spent running itself for a period, set against everything it earned in the same period. Written as a share of income, so the base has to be named or the figure means nothing. for the year. A ratio without its base is a number without a meaning, so note that this one is stated on total income and on nothing else. Now the three absences, named in one place rather than worked around. There is no count anywhere of the accounts those deposits sit in, so a cost per account cannot be worked here at all. The material carries no split of the Rs 5,040 crore operating expense line, so no share of it can be attributed to verification. And it carries one year and no second period, so no before and no after exists against which any change could be tested.
The more useful thing stands in its place: the exact list of what would have to be asked for. A count of accounts, a split of the operating expense line, and two periods. A reader who knows those three names can walk into any real arrangement and ask three specific questions. Three specific questions are worth considerably more than a plausible number nobody could have checked.
Hand yourself the missing figures one at a time, and watch which rows become workable
Every button below supplies the existence of a figure and never its value. The material does not carry those values. Switching a button on fills in what the calculation would be and leaves the value slot empty. An honest sheet looks exactly like that. At the starting setting, with all three switched off, the sheet shows precisely what the table above shows and nothing more.
With none of the three figures handed over, one row of four is workable: Rs 5,040 crore of operating expenses over Rs 9,840 crore of total income, which is 51.22 per cent for the year. The other three rows are waiting on a split of the expense line, a count of accounts and a second period, and none of them is supplied here.
Educational illustration. Every figure here belongs to Suvarna Commercial Bank Limited, and every one of them is for a single stated year. Switching a button on never produces a number. It names the calculation and leaves the value empty, and no substitute for the missing value is brought in from anywhere else. The starting setting reproduces the table above to the decimal. A worked example and an interactive that disagreed with each other would make both of them worthless.
Deposits stand at Rs 1,92,000 crore, total income at Rs 9,840 crore and operating expenses at Rs 5,040 crore, all for one year. Which of these can be worked out about the cost of a single check?
What happens when a check does not complete?
Mechanically, two things can happen and both of them are reports about evidence. A comparison that finds no record returns nothing, and a comparison that finds a record which does not agree with the details presented returns a mismatchA record was found, and it does not say the same thing as the details that were presented. Two written things disagree; which of the two is out of date is a separate question the comparison never answers.. Neither of those is a verdict. Neither of them is even an opinion. One reports the absence of a record and the other reports a disagreement between two written things, and the comparison never says which of the two is the one that is out of date.
The mechanical consequence is simple: the account does not open, and the step stays outstanding. And here is the rule: a check that does not complete is a statement about evidence and never a statement about a person. An arrangement that treats it as the second has drawn an inference its own process cannot support. The process it ran was a comparison, and a comparison that finds nothing has reported the absence of a record and nothing else at all.
The route matters more than the diagnosis, and the route is the thing to go and find. A record that does not agree with the details presented is corrected at the register that holds it. The register is a different place from the bank or intermediary that ran the check. And a complaint about the arrangement's own handling of the step has a route, and a time inside which it must be answered. Both belong to the Reserve Bank of India at rbi.org.in, and both change, so a stale version of either would point somebody at the wrong counter.
A comparison returns a mismatch between the details presented and the record held. Which of these has just been established?
What goes wrong when a completion figure is read as a conclusion?
The error that costs the most is not made by anybody near the counter. The person who makes it is whoever is handed a completion figure for a verification step and has to explain it before the end of the day.
The reading that leaves the route exactly as it was
A figure comes back showing that a share of the checks begun at one step did not complete. The reading taken is that something about the parties at that step explains it. The response that follows is aimed at those parties: more reminders, more prompting, more chasing.
Meanwhile the three things the mechanism actually points at have not been looked at even once. Whether the register holds a record to compare against at all. Whether the details recorded there agree with the details being presented. And whether the evidence the arrangement will accept is evidence that exists in that form.
The cost, stated plainly: the number was read as being about people rather than about evidence, so the route is never redesigned. The same step stalls again next quarter, and the figure is read the same way again.
The second cost is larger and slower. An arrangement that treats a stalled check as a conclusion about somebody has drawn an inference its own process cannot support, and it will keep drawing it. Nothing in the reporting ever contradicts a reading nobody tested. The fix is one line: a completion figure for a verification step is a reading on evidence and on the route, so it is read against the register and against the accepted forms before it is read against anything else.
How does somebody handed a completion figure actually use any of this?
The three questions that turn a stalled step into something that can be fixed
Whoever reviews a verification step, whether that is somebody inside the arrangement, somebody assessing how well its processes run, or somebody deciding whether to fund the building of a new route, has the same three questions available, and they are asked in this order because the order narrows the search fastest.
First: at the step where completion falls away, does a register hold a record for the fact being established at all? If it does not, no change to the arrangement's own process moves the number. The record is what is missing, and the arrangement cannot supply it. Second: where a record is held, do the details in it agree with the details being presented? A concentration of disagreement usually points at one register, one field, or one period during which something was recorded differently, and that is a specific and fixable thing. Third: does the evidence the arrangement accepts exist in the form the arrangement wants it in? A form requirement that nothing satisfies is a design fault in the route rather than anything else.
Notice what all three have in common. Each one names a thing that can be inspected, and each has a different route out. Three separate routes out are what make the questions useful: they turn a single unexplained percentage into three separate questions with three separate answers, and at least one of those answers is almost always something the arrangement can change.
Who sets what the check asks for?
Six conditions have been touched above. An authority fixes each of them, and each one changes when that authority changes it. The sheet below carries the condition, the body that fixes it, and a blank where the value would be.
Six conditions, the body behind each, and six values left blank to be filled in
| The condition | The body behind it | The value |
|---|---|---|
| Identification obtained and checked before an account opens | Reserve Bank of India, rbi.org.in | confirm at source |
| Proofs of identity and of address that may be taken, and the form they take | Reserve Bank of India, rbi.org.in | confirm at source |
| Frequency at which a record on file is confirmed again, and what forces it sooner | Reserve Bank of India, rbi.org.in | confirm at source |
| Conditions riding on an account opened under a lighter check, and what it may do | Reserve Bank of India, rbi.org.in | confirm at source |
| Retention of the record of a completed check, and the form it is kept in | Reserve Bank of India, rbi.org.in | confirm at source |
| Identification taken before an account with a securities intermediary opens | Securities and Exchange Board of India (SEBI), sebi.gov.in | confirm at source |
Every value in that column is fixed by a body that revises it, so the column carries an address instead of an answer. A treatment of a verification check is precisely where somebody turns up hoping to find a list of documents printed out. The body named alongside each row composes that list and revises it, so a reader who copied a stale version away could send themselves to the wrong counter with the wrong thing in hand. An address that can be checked is worth more than an answer that cannot.
Suppose the current list of evidence acceptable for this check in India is needed. Where does somebody go for it, and on what grounds?
Seven addresses handed over in place of seven values
