Zach reports that a professor at Johns Hopkins University has successfully been able to read, decrypt and forge Mobile’s Speedpass RFID tag after only a close pass with a reader and laptop.

The Speedpass tag is a small key fob which is linked to a credit or debit card. It can be read at the pump or register by waving the tag near an RFID reader.

Mobile has been quick to point out that this type of tagjacking has yet to be used maliciously, but like Zach I think it naive to consider it more than a matter of time.
