The tag can be read inside a case, carton, box or other container, and unlike barcodes, RFID tags can be read hundreds at a time; barcodes can only be read one at a time using current devices. Some RFID tags, such as battery-assisted passive tags, are also able to monitor temperature and humidity.
Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number that can be linked to information contained in an external database, such as identity document , criminal record , medical history ...
X-ray image of a microchip implant in a cat. 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 (passive integrated transponder) tag.
The microcontroller can perform a variety of computing tasks, including sampling sensors, and reporting that sensor data back to the RFID reader. WISPs have been built with light sensors, temperature sensors, and strain gauges. Some contain accelerometers. [2] WISPs can write to flash and perform cryptographic computations.
On roadways around the United States, radio-frequency identification (RFID) transponders, supporting transceivers, antennas, and video cameras are the current standard for the collection of toll fees. This technology was invented during the 1970s and was implemented throughout the 1980s and 1990s.
This can work even retrospectively — given that a stolen credit card can easily be invalidated with a phone call to the issuing bank, the motivation to steal one is reduced. In the case of vehicle theft, the best deterrent to theft is in the installation of an approved vehicle anti-theft passive immobilizer .
RFID on metal (abbreviated to ROM) are radio-frequency identification (RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all.
The Texas Instruments digital signature transponder (DST) is a cryptographically enabled radio-frequency identification (RFID) device used in a variety of wireless authentication applications.
