I'm new to RFID blocking and find it interesting. I came across this video to learn more and just have 2 questions https://www.youtube.com/watch?v=NKwJwOm3bfI
If my intention is to create a DIY wallet with this setup:
Scannable card #1 |SHIELD| Card to protect |SHIELD| Scannable card #2
Is there a specific type of RFID Shield I should look for? one that doesn't 'jam' all nearby cards, as I want card #1 #2 to be functional? Is there a term for that for an easy further google search?
