Experts warn RFID chips raise growing concerns

A few years ago, anyone suggesting you line your wallet with copper mesh to keep others from secretly scanning your credit cards for private information would have been relegated to the tinfoil-hat brigade, Area 51 fanatics or the lunatic fringe.

These showed everyday people that just about everything important in their personal and financial world is embedded in a database, usually one they carry around in a back pocket or purse in the form of an RFID, or Radio Frequency Identification chip.
