Direct answerA withdrawal travels back along the rails that funded the account, up to each rail’s cap and only in the account holder’s name. That is why it may not reach a bank account the reader prefers, why it may arrive as several payments, and why a rail that has gone leaves money that has to be re-routed.

The questions, in full

q01

Why will it not just go to my bank account?

Because the money has to travel back the way it came. A card deposit creates a cap on the card, and the bank account was never used to fund the account, so it has a cap of zero until a deposit settles on it. The bank can still receive the released part of a balance - the amount above every cap - if the operator nominates that route for released funds.

q02

I have used the card for years - why does it say the rail does not exist?

No. A rail opens when a deposit on it has completed, not when a card is saved to the account or used elsewhere. A saved card that has never funded the account has a cap of 0.00 and cannot carry a withdrawal at all, which is why a long-standing destination can be refused as if it did not exist.

q03

I put in 10.00 to unlock it, so why can I still only take out 10.00?

A cap exactly equal to the deposit. A 10.00 test deposit opens the rail and creates 10.00 of capacity - 2.5% of a 400.00 request - while the rest of that request still has to travel on rails that took money in. Its real value is proving the destination and the name before a larger payment is attempted.

q04

Why did one withdrawal arrive as three payments?

Because each rail may return only what it paid in. A request larger than the first rail’s cap moves on to the next rail, and each payment is one rail’s cap being returned. Three payments mean the request was met by three rails, not that it was divided by an error or charged three times.

q05

Can I choose which rail the money goes back to?

Sometimes, within the caps. Operators differ: some allow a reader to nominate a destination as long as it has completed a deposit and carries the right name, and others apply a fixed order. Neither approach lets a payment exceed a cap or reach a rail that has never paid money in.

q06

The card I paid with has expired - where does the money behind it go?

The cap remains and cannot be paid, so the money behind it stops until the operator re-routes it. Three routes exist: hold the money until a replacement rail is provided, re-route it against a signed indemnity with a fee and a wait, or open a fresh rail with a small test deposit - which creates only that small cap and leaves the rest where it was.

q07

Why does the withdrawal not go to the account I deposited from?

Usually because the deposit was made from somebody else’s card or bank account. The payer name does not match the account holder, so that rail cannot pay out, and its cap is frozen while the relationship is checked. The rest of the account is unaffected and can still be withdrawn.

q08

Is money above the caps lost?

No. It is called released money on this desk and it is fully payable - it simply has no rail to travel on because every rail has already returned what it took in. It goes by whatever route the operator nominates for released funds, which is a separate policy with its own timeline and sometimes its own fee.

q09

Why was a small withdrawal split but a larger one was not?

Because the count of payments tracks the rails a request reaches, not its size. A proportional rule makes every open rail pay a fraction of any request, however small, while a large request on a single-rail account is one payment. The cap table, not the amount, predicts the count.

q10

Does withdrawing on the same rail as a deposit restore its cap?

It reduces it, and a later deposit on the same rail raises it again. The cap is a running balance of completed payments in and out, so a reader who deposits and withdraws repeatedly on one card can cycle the same capacity indefinitely, while a reader who deposits once and withdraws once has used that rail up.

q11

Can a reversed or charged-back deposit change my cap?

Yes, and it reduces it. A reversal removes the deposit retrospectively, so the rail’s paid-in figure falls and its cap with it. If that rail has already returned more than its reduced paid-in figure, the operator will normally say so before the next withdrawal, because it has paid out more than it received on that rail.

q12

Where is the rule written, and which version applies to my withdrawal?

Usually in the withdrawal section of the terms, sometimes also required by a licence condition and often explained - without binding effect - on a help page. The version that governs is normally the one in force when the request was made, subject to any notice period the terms set for changes.
