You don’t need RFID protection in your wallet

It seems like a creepy and very 21st-century crime — your credit cards being invisibly read and stolen by a futuristic gadget as you walk down the street. A solution is a kind of armour — keeping credit cards with radio-frequency identification (RFID) technology behind a discreet aluminum shield in a wallet. Mountain Equipment Co-op, for example, sells nearly two dozen wallets, bags, money belts and backpacks equipped with RFID protection. But, here’s the thing: though it is possible to read some credit card data remotely, there’s not a lot thieves can do with that data.
