What are some of the key attributes of RFID?
Key attributes of RFID include: Because tag data is transmitted and received by radio frequency, RFID does not require line-of-sight to read and write the tag data. RF signals also are capable of traveling through a wide array of non-metallic materials. Most RFID systems can simultaneously capture data from many tags within range of the antenna. This unique feature is known as “simultaneous identification.” RFID tags can be read very rapidly. RFID readers are capable of capturing tag identification codes at a rate of up to 1,000 tags per second. RFID tags can be encased in hardened plastic coatings making them extremely durable and able to be tracked through harsh production processes. They can be read through grease, dirt, and paint. RFID tags can store large amounts of data. High-end RFID tags can contain up to one megabyte of memory (one million characters), although most tags only contain a small fraction of this memory, perhaps as little as 64 bits. Some RFID tags are able to supp
