Tech Tip

Credit Card Security

 

With the recent Equafax breach, we must be very careful of ALL security these days. Did you know there are low tech ways to protect your credit cards?

RFID embedded cards use radio frequencies to transmit data. These cards have been in use in

Europe for many years but are just coming into use in the U.S. The idea is that consumers should be able to use these cards at stores and restaurants to pay for purchases without having to swipe the card through a scanner. Many people remain concerned, however, that the RFID technology may also allow thieves to use scanners to intercept the radio waves and steal the card's

information. While technology has made significant security improvements in the past few years, some concerns still exist. Here are some tips for keeping your cards safe.

Place your RFID cards next to each other in your wallet. This can make it more difficult for thieves to read a particular card, but the protection is limited.

Carry your RFID cards in a front pocket. If you usually carry your credit cards in a wallet in your back pocket, you are potentially more vulnerable to thieves who could step up behind you with a scanning device. If you switch the cards to a front pocket, you will tend to be more observant of people in front of you and are less likely to become a victim.

Monitor your credit card statements for usual activity or errors. This may not actually prevent thieves from stealing information from your card, but monitoring your statements regularly will help you and the credit card company identify any unauthorized purchases and can limit your

potential losses. Some sources say that regular monitoring of your credit card statements is

actually the “best” protection against identity theft.

Purchase an RFID shield wallet or sleeve for credit cards. There are several commercial products available that claim to block RFID scanners from obtaining your personal information. These may be individual sleeves for your RFID cards or wallets that are lined with material to block scanners.

Make a foil shield. This is the “low-tech” way to go, but it’s cheap and easy. Cut two pieces of paper or cardboard into the size of a credit card, wrap each piece with aluminum foil, and carry them in your wallet around your credit cards. The aluminum will disrupt most electronic signals.
