A California company, Kena Kai, is offering a new line of wallets for people carrying RFID-enabled smartcards. [via Contactless News]

Kena Kai's DataSafe Wallets(tm) are most likely based on the Faraday Cage principle, which Emvelope's RF-shielding wallet insert supposedly uses.

A similar solution, Shelly, consists of a card which temporarily disables a smartcard's communication. These cards come in "Hello Kitty" cutesy themes.[via RFID in Japan]
