#26- Beware of Thieves You Can't See- Manage RFID Risks

What I learned this time around:

1) Radio frequency ID chips are imbedded in newer credit cards and passports, allowing transactions without touch. Thieves can also read these, just by getting close to you in a crowd, and then they can imprint your information on a blank credit card and go on a shopping spree.

2) First step is simply to know if you are carrying an RFID-enabled credit card. Find out by calling your credit card company, reading the card agreement, or checking your cards for the presence of an RFID chip or RFID logo, which looks like a series of expanding ripples or waves.

3) If you have RFID cards, leave them at home and use other cards, or alternative payment systems, such as Square or Goggle Wallet.

4) If you have to bring RFID cards, you can block random readings using protective card holders, wallets, or by wrapping the cards in aluminum foil or metal.
