I’m using RFID-protection-sleeves made of cryptalloy for my contactless-cards; they shield good against unwanted scanning, but they also make it hard to take the cards out (yeah I’m a bit clumsy)
I bought myself some cheap RFID-shieldcases from “overseas” (probably simple alluminium, but also shielding). Of course, those things have a very small “grip-area” for the cards, too.
I now had the idea of “cutting the sleeves out a bit”, so i can easily grab the cards. But I don’t know how much i can cut out without negating the shielding, as I have no idea where the RFID-Antennae in the cards are…
Is there a certain area that should be covered? Or do the antennae (not only revolut cards) go over the whole area of the cards?
BTW: it would be great if Revolut would ship the cards with RFID-shielding sleeves - the Chaos Computer Club demonstrated over a decade ago how easy those things can be spoofed and “sniffed out”… And those sleeves aren’t THAT expensive
Edit: typos. I fixed as many I could.
