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.
