RFID (Radio Frequency Identification) Skimming is a form of digital theft, which enables information from RFID based smart cards to be read and duplicated. It can be used as a form of wireless identity theft or credit card theft among other forms of information theft. Typically it works by illegitimately reading of RFID chips at a distance using a cheap RFID reader device, which downloads the card information. From there, it can be written to a new blank card, which then operates in the same manner as the original legitimate card.
