Credit card chips can be duplicated
How do I protect or protect my broken card from thieves? (Block RFID transmitter)
I read an article on the news today called "Police Warn Credit Card Chips Make It Easier for Thieves".
Because the chips transmit a radio signal (an RFID), it appears that this signal can be picked up by a device on a thief's cell phone or laptop and used to steal your account information or personal information.
History claims that by getting "card protectors or wallets" you can improve your protection.
What materials enable this and other options in terms of RFID shielding / protecting my cards?
I've found quite a few wallet manufacturers that offer this protection, but how do I choose ...
Can I just wrap my wallet in aluminum foil (shiny side out or in)?
The chips do not transmit anything unless they are in place very close (millimeters) to an RFID reader that induces them.
You can protect them by adding a barrier to keep the induction from working. There are several (very cheap / free, like this one) products for this, and many wallets have the protection features these days. Wrapping in foil might also help.
