The Truth About RFID Tags

RFID chip pulled from new credit cardImage via WikipediaI would have never believed it if I didn't do the research first. Thieves can steal information from your credit cards! They can do this through the use of RFID technology. Conventional credit cards do not have this, but new ones do.

RFID is a new technology that was used for tracking and storing information for scientific research. It was only later that it became a useful way of storing and sending information for business.

Credit cards with RFID chips are convenient for both consumers and merchants because the cashier does not have to take your card and swipe it. If the merchant's POS device has an RFID scanner or reader installed, then it can detect the RFID tag in your card and start sending and receiving radio wave signals up to a range of 18 inches.

If you are very conscious of protecting your self from identity thefts, then an RFID wallet might not be a bad idea. However, you also have the option to ask your bank or credit card company to issue a non-RFID card.

Better yet, if you want a very convenient payment process, you should consider using your mobile phone to pay. RFID tags can be embedded in microSD cards. The tags contain your bank information.

The good thing with microSD cards is that you only insert and activate them when it's time to pay. The RFID tags in credit cards are on all the time and makes them vulnerable to thieves who can put together a crude scanner, which they can hide in their pocket while walking through a crowd or hide behind bushes or in corners to catch information from passersby.
