Usage of weak encryption codes in RFIDs - 0 views

Mohammad A on 05 Dec 10In big corporations such as Wal-Mart, the use of RFIDs has increased, but the disadvantages of RFID is now a serious issue. With the use of RFIDs on items, the customer is able to avoid waiting at a register, and the RFID will charge the person's credit-card. Yet the tags embedded in the items bought, such as clothing, can be tracked down by the store management systems, risking customers' security and privacy. Since RFIDs do not require a power supply or batteries to operate, all that is needed is a wireless scanner, which Wal-Mart's managing system uses to keep track of the items. Privacy has now become a major issue within the use of RFIDs for many Wal-Mart customers. Also, in many credit cards and "gas-cards", RFIDs are being used, yet the information on the tags also stays within the system. At airports, many modern passports are now using RFID tags that can be scanned from a range as far as 30 feet. Thus this results in chaos for the passengers, and an issue in being able to control the airport security properly.

Ram Bhadra on 06 Dec 10Large scale businesses like Wal-mart and government authorities in passport make use of sophisticated RFIDs which make the data stored in them or to be accesses through them safe, which helps them keep their business data or data of the clients(in some cases passport holders) safe, however many corporates make use of cheap RFIDs which have a weak encryption code to protect them. This code can be broken easily and hence the client of that RFID is vulnerable to hackers. Ford for example makes use of RFIDs manufactured by Texas Instruments, in their car keys. These RFIDs are protected by very weak codes, hence it is easy for thieves to break the code and steal cars.
