Most slim wallets are designed to hold cash and 6-7 cards. I need one that only holds 2 cards max, and has no space for cash. Preferably a vertically loading one, so I can insert the card into the wallet straight out of a chip card reader, before it's even done reading.
Kinda like this, but this one has a backside with 2 additional layers of material: https://www.amazon.com/dp/B07GNX42Q2
This one is cool too, but has 2 layers of fabric and holds up to 8 cards, which means it will be loose with 2 https://www.amazon.com/dp/B07FK7DFH4
