Items and people can be identified, tracked, and communicated using RFID tags, a form of the radiofrequency tracking device. As a general rule, RFID tags can contain a wide range of information, from a short description to serial numbers to to even pages of data. Some RFID tags have cryptographic security capabilities that allow for high-level verification and authentication. Radio-frequency identification (RFID) tags come in three varieties: low, medium, and high-frequency (UHF).
Radio-frequency identification (RFID) tags send and receive data via an antenna and a microchip, which is also known as an integrated circuit (IC). The RFID reader's microchip can be programmed with any information the user desires. An RFID tag is a tiny piece of electronic equipment that can be attached to a person.
Battery-powered and passive RFID tags are the two most common types of tags. Batteries are used to power battery-operated RFID tags, while passive RFID tags rely on electromagnetic energy transmitted from an RFID reader instead. RFID tags that are powered by batteries are sometimes referred to as "active" RFID tags.
Only a small percentage of RFID tags are active, which means they have their own transmitter and power source. Active RFID tags. It is common for these tags to be heavier and more durable, as well as more expensive. A beacon used for RTLS, medical monitoring, or theme park attendance is an example of an active RFID tag.
