How do you fulfill the bank's requirement to keep slips (if any in the contract)?

Question

Payment cards

Hello.
After one of the, as I thought, adequate banks * refused to investigate the chargeback until I provided all the slips for the last three months (two (!) slips were not enough **, I changed the bank, switched to chipped cards *** ) and began to collect slips more thoroughly.
Yes, such a clause was in the contract and I drew attention to it when signing it.
As it turned out, this is not a requirement of a particular bank, many have it (implicitly).
So. For two months, a decent pile has accumulated (I specified in support, scans are fundamentally unsuitable).
Perhaps someone has already solved the problem? Are there any general recommendations / life hacks (I just put it in a box, collecting neat piles only when it was completely clogged) how to collect them so as not to gouge a single slip?
*) in the top five of the national rating of banks.ru
**) I printed the missing slips on a regular receipt printer, no one will check a pack of 150 pieces and authorization codes on them. The chargeback is successful, since the signature on the fraudulent check is clearly not mine.
***) if anyone is interested, it seems to me that a copy of the map was taken in the rostix on Mayakovskaya. This is the only place where the payment was authorized by a regular reader next to the touchscreen + signature, and not a special one. terminal. After that came fraudulent payments.

Answer 1

A simple box into which I throw everything related to the cards.
When it fills up, I disassemble and throw away the old
ones. By the way, thermal printing and years later you can read.
The originals may be needed for the examination of the signature, since it is no longer possible to distinguish a facsimile from a signature on a scan.

Answer 2

What bank, could you tell?

Answer 3

Alpha bank or not?
I never keep slips, I thought contesting transactions was easier.

Answer 4

I keep all checks and slips for a month. Warranty ones are longer. We canceled ucs “with a reader next to the touchscreen + signature” and said to install terminals ... You can probably store it, but usually it’s thermal paper, which becomes unreadable over time. The slip contains code to help resolve issues faster. "Scans are not good" - generally nonsense.

Answer 5

Keeping them can be very useful if utility bills are paid by card. In such offices, it is checks that are needed, and since. thermal paper fades in half a year, it is almost impossible to prove something. Paid, make a scan ... at least you yourself will know for what and when you paid. Anyway, as a legal document, a check cannot be used ... if there is a lawsuit, then it is necessary to take an extract from the card account from the bank, always with a seal ...
