My bank card started to crack and the bank wouldn't replace it until 2026, so I designed this to hold it together for a year or so.  It fits very snugly on the end/edge of the card (should fit debit/atm/credit card standard size) so it shouldn't fall off, even just with a press-fit.  That said, it also CAN be removed quickly/easily if you need to ‘swipe’ the card for some reason.  I've been using it for several months and it really seems to be doing the trick.
