Dave- two security stories popular on Digg tonight:
http://rfidanalysis.org/
"The Texas Instruments DST tag is a cryptographically enabled RFID  
transponder used in several wide-scale systems including vehicle  
immobilizers and the ExxonMobil SpeedPass system. This page serves as  
an overview of our successful attacks on DST enabled systems. A  
preliminary version of the full academic paper describing our attacks  
in detail is also available below."
and

"... Wallace, IT director at AAA Reading-Berks in Wyomissing, Penn.  
has been bringing a card reader with him on business trips to see  
what's on the magnetic strips of his hotel room access cards. To his  
dismay, a surprising number have contained his name and credit card  
information - and in unencrypted form."
