In 1945, Léon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information.

This figure includes tags, readers, and software/services for RFID cards, labels, fobs, and all other form factors. In 2014, the world RFID market was worth US$8.89 billion, up from US$7.77 billion in 2013 and US$6.96 billion in 2012. These concerns resulted in standard specifications development addressing privacy and security issues. Since RFID tags can be attached to physical money, clothing, and possessions, or implanted in animals and people, the possibility of reading personally-linked information without consent has raised serious privacy concerns. Tags can also be used in shops to expedite checkout, and to prevent theft by customers and employees. For example, an RFID tag attached to an automobile during production can be used to track its progress through the assembly line, RFID-tagged pharmaceuticals can be tracked through warehouses, and implanting RFID microchips in livestock and pets enables positive identification of animals. RFID is one method of automatic identification and data capture (AIDC). Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Passive tags are powered by energy from the RFID reader's interrogating radio waves. This number can be used to track inventory goods. 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. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. Refer to the Safety and Handling documentation for cleaning and drying instructions.Radio-frequency identification ( RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. AirTag is splash, water, and dust resistant and was tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529 (maximum depth of 1 meter up to 30 minutes).Battery life varies with usage, environmental conditions, replacement battery manufacturer, and many other factors actual results will vary. Battery life based on an everyday use of four play sound events and one Precision Finding event per day. Testing conducted by Apple in March 2021 using preproduction AirTag units and software paired with iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max units running preproduction software.Precision Finding is compatible with iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13, iPhone 13 mini, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 14, iPhone 14 Plus, iPhone 14 Pro, and iPhone 14 Pro Max.Have a question?
