The clipped tag is a radio frequency identification (RFID) tag designed to enhance consumer privacy. RFID is an identification technology in which information stored in semiconductor chips contained in RFID tags is communicated by means of radio waves to RFID readers. The most simple passive RFID tags do not have batteries or transmitters. They get their energy from the field of the reader. They transfer their information to the reader by modulating the signal that is reflected back to the reader by the tag. Because tags depend on the reader for power their range is limited, typically up to 10 meters (33 ft) for UHF RFID tags.
Today, the public uses RFID tags for many applications including electronic toll collection, E-ZPass for example, or the Speedpass which is used as a credit token for the purchase of gasoline. The retail supply chain uses RFID tags to monitor the passage of pallets and cases at loading dock doors. The expectation for the future is for RFID tags to be used for the labelling of items for retail sale. Concerns for individual privacy have been raised because the RFID tags may be read by invisible radio waves without the knowledge of the holder of the tagged item.
The privacy-protecting RFID tag, the “clipped tag” has been suggested by IBM. The clipped tag puts the option of privacy protection in the hands of the consumer. After the point of sale, a consumer may tear off a portion of the tag, much like the way in which a ketchup packet is opened. This allows the transformation of a long-range tag into a proximity tag that still may be read, but only at short range – less than a few inches or centimeters. The modification of the tag may be confirmed visually. The tag may still be used later for returns, recalls, or recycling. The clipped tag was listed among The Wall Street Journal Technology Innovation Winners for 2006. Two US patents were issued for this invention in 2007.
Other mechanisms designed to protect privacy for RFID item tagging for retail use are the EPCglobal kill command and the RSA blocker tag.
The concept of the clipped tag was first introduced in a paper authored by IBM researchers Paul Moskowitz and Guenter Karjoth in 2005, RFID Journal, November 7, 2005. In their paper, presented at the 2005 ACM Workshop on Privacy in the Electronic Society, the authors suggest that by providing the consumer with a means to shorten the antenna, the read range of the tag may be reduced from many meters to just a few centimeters. Several mechanisms were suggested. The mechanisms included perforating the tag like a sheet of postage stamps to allow the tearing off of a portion of the antenna. Another proposed mechanism was to manufacture the tag antenna with exposed conducting lines which could be scratched off by the consumer.
IBM teamed up with Marnlen RFiD, a manufacturer of RFID labels, and Printronix, a maker of RFID printers, to demonstrate prototypes of the Clipped Tag, Wired News, May 1, 2006. The tag took the form of a garment hang tag with v-shaped notches in the edges and perforations to direct the tearing of the tag. Reactions by RFID privacy experts were favorable to the invention. According to Wired, Robert Atkinson, president of the Information Technology and Innovation Foundation, said "The Clipped Tag shows that IBM is addressing privacy concerns, even those that are unreasonable." Subsequently, IBM and Marnlen RFiD announced that Marnlen had licensed the technology from IBM and was shipping samples to select users, RFID Update, November, 2006.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.

Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s.
A microchip implant is an identifying integrated circuit placed under the skin of an animal. The chip, about the size of a large grain of rice, uses passive radio-frequency identification (RFID) technology, and is also known as a PIT tag. Standard pet microchips are typically 11–13 mm long and 2 mm in diameter.
Automatic identification and data capture (AIDC) refers to the methods of automatically identifying objects, collecting data about them, and entering them directly into computer systems, without human involvement. Technologies typically considered as part of AIDC include QR codes, bar codes, radio frequency identification (RFID), biometrics, magnetic stripes, optical character recognition (OCR), smart cards, and voice recognition. AIDC is also commonly referred to as "Automatic Identification", "Auto-ID" and "Automatic Data Capture".
An RSA blocker tag is a RFID tag that responds positively to all unauthorized requests, thus blocking some scanners from reading any RFID tags placed nearby. The tags are designed to protect privacy, and are supposedly unable to be used for theft, denials of service, and other malicious uses.

RuBee is a two-way active wireless protocol designed for harsh environments and high-security asset visibility applications. RuBee utilizes longwave signals to send and receive short data packets in a local regional network. The protocol is similar to the IEEE 802 protocols in that RuBee is networked by using on-demand, peer-to-peer and active radiating transceivers. RuBee is different in that it uses a low frequency carrier.
Wireless identity theft, also known as contactless identity theft or RFID identity theft, is a form of identity theft described as "the act of compromising an individual’s personal identifying information using wireless mechanics." Numerous articles have been written about wireless identity theft and broadcast television has produced several investigations of this phenomenon. According to Marc Rotenberg of the Electronic Privacy Information Center, wireless identity theft is a serious issue as the contactless (wireless) card design is inherently flawed, increasing the vulnerability to attacks.

Dynamic Intelligent Currency Encryption (DICE) is a technological concept designed to enhance the security of paper currency. The system tracks and monitors banknotes in circulation using identifiable characteristics, allowing for the remote devaluation of banknotes involved in fraudulent activities or criminal transactions. Developed in 2014 by the British-Austrian technology company EDAQS, DICE involves the use of Machine Readable Codes (MRC) or Radio-Frequency Identification (RFID) tags embedded in banknotes. These banknotes are then registered to a centralized system to increase security and reduce the risk of forgery tags. These banknotes are then registered to a centralized system, purportedly rendering them secure and resistant to forgery.
