RFID vulnerable to attacks, researchers say By Tom Espiner Special to CNET News.com

Researchers say they have proven that effective attacks can be launched against radio frequency identification tags.
In tests, standard "Generation 1" RFID tags and readers were unable to function after they were overloaded with data, researchers at Edith Cowan University in Perth, Australia, said in a report published this month.
"Vulnerabilities in the newer UHF style of RFID tags have been found and are of concern for anyone trying to implement an RFID system that would have 'mission critical' or human life issues involved in it," warned academics in the SCISSEC research group at the university.
Although many companies are testing RFID tagging in their supply chain, the tags are not commonly used in life-critical situations. However, the tags are used by the U.S. military to track supplies.
"Generation 2" standard RFID tags could also be disrupted, according to the researchers. Generation 2 tags are more sophisticated than Generation 1 tags, and can operate at four different speeds.
RFID relies on tags being identified by readers when they are within range. Readers communicate with the tags by hopping between a number of channels within an allocated band of frequencies. It was thought this provided security because the reader could hop between frequencies when encountering interference.....

看起來只是讓整個系統無法進行交易，應該沒有安全上的影響。
