Does this have to be placed over your cards in your wallet for it to work ?

Easy to Use: Simply place the rfid blocking card next to ID, credit card, debit card, passport for protection.

Does the card use active or passive technology?

No moving parts, no battery, so I would describe it as passive.

How would i know what frequency my cards use? this product won't work with: frequency from 100khz to 125khz.

The best bet is to contact the manufacturer.

Has anyone tested these?

Only testing I been able to do is use them and hope they are really more then a aluminum card. So bad things so far.

Buena opción

De momento puedo decir que funciona con las pruebas rudimentarias que le realizé con la tarjeta de movilidad de la CDMX, al tener juntas las tarjetas tanto de movilidad como de bloqueo no las lee, falta probar con terminales
