Target Stores Security Breach..

Most of us have heard of the security breach for the Target super-store chain. NY Times article:
Some of the stolen card numbers have shown up in other countries now. The banks issuing the credit cards are replacing them with new cards, different numbers.
As a sort of fall-out action, RFID microchips may be embedded in new credit/debit cards in the near future. That may be problematic, as the card need not be 'swiped' on a reader.. the RF signal can be captured from up to 10 feet away, with a snooping device!! Similar problem with an Easy-Pass toll system in some cities. Card ID is read in locations where there are no toll machines!!!! "Traffic survey"?? :o
One solution is to shield the card or tag in a metallic sleeve (static bag?) until needed, for security. With standard credit/debit cards, a paper sleeve will protect the data stripe from damage. Rubbing the stripe on another card's stripe may corrupt the data. And certain types of wallets, especially eel skin, can destroy the data stripe info when slipping the card in or out of its pocket!!
There also is another version of credit card protection.. a small capacitive reader on the card, which compares the user's fingerprint to a memory image. If identical, the card is usable. If not, 'access denied'.

True, evasive.. but even genuine electric eel skin should not retain any static electricity generating properties, after the tanning process! Yet the process may leave a static-generating surface on any type of hide. Even cowhide, deerskin or snake skin. With the insert and removal of the plastic card on a polished surface, possibly enough of a static field can be generated. But no 100% consensus either way.
A plain paper sleeve is the best protection for any type of credit card.
As noted in some search link results, a magnetic closure device may be used on some wallets. Not a good idea, if credit cards are kept in them! Non-ferrous metal is the only choice. Or Velcro.

A bit off topic, but static electricity is a nuisance at times.. and very dry air is its favored element. Triboelectric Properties:
