The new cards have chips imbued with radio-frequency identification, or RFID,

Big Brother, thy name is 'RFID'.

Especially when paired with your cell phone with it's built-in capability to locate you within a few feet via GPS. From the article:

MasterCard's PayPass comes on a regular-sized card that also has a magnetic stripe for swiping if need be. MasterCard also has done tests in Dallas with Nokia Corp. in which the RFID chip is embedded in the plastic casing of a cell phone.
