Can RFID Tags be duplicated?
Yes it is possible, but very unlikely. The technological hurdle is intentionally very high, making it impractical in virtually all cases. Counterfeiting of tags is also detectable by the systems used to read tags and verify authenticity through a variety of validation procedures. One such validation procedure is to check for records of copies having been previously used. More elaborate schemes involve secure challenge and response protocols involving secret numbers used as encryption keys.
