100pcs 125Khz RFID ID Card for Access Control System Or Time Clock

Product Information

Passive tags are powered by energy from the RFID reader's interrogating radio waves. 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.

Archived from the original on 2014-03-30 . Retrieved 2007-03-27. Tags may either be read-only, having a factory-assigned serial number that is used as a key into a database, or may be read/write, where object-specific data can be written into the tag by the system user. Field programmable tags may be write-once, read-multiple; "blank" tags may be written with an electronic product code by the user. [20] Fisher, Jill A., Monahan, Torin (2012).

There are contradictory opinions as to whether aluminum can prevent reading of RFID chips. Some people claim that aluminum shielding, essentially creating a Faraday cage, does work. [140] Others claim that simply wrapping an RFID card in aluminum foil only makes transmission more difficult and is not completely effective at preventing it. [141] The NFL has a (RFID) Chip on its shoulder". News Surgo Group. Archived from the original on 2015-09-06 . Retrieved 1 September 2015. In 1945, Léon Theremin invented the "Thing", a listening device for the Soviet Union which retransmitted incident radio waves with the added audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a covert listening device, rather than an identification tag, it is considered to be a predecessor of RFID because it was passive, being energised and activated by waves from an outside source.

As the owner of an item may not necessarily be aware of the presence of an RFID tag and the tag can be read at a distance without the knowledge of the individual, sensitive data may be acquired without consent.

Where ship, rail, or highway tanks are being loaded, a fixed RFID antenna contained in a transfer hose can read an RFID tag affixed to the tank, positively identifying it.
