RFID Scanners: Can Metal Protect?

[Bacle2]

Hi, All:

Sorry if this is not the right forum.

I was just reading that the information in one's wallet can be stolen using an

RFID scanner. Also, metal , aluminum supposedly can be used to protect, i.e.,

I assume, block the signal from coming into the wallet. Is this all correct?
