About this deal

An Electronic Product Code (EPC) is one common type of data stored in a tag. When written into the tag by an RFID printer, the tag contains a 96-bit string of data. The first eight bits are a header which identifies the version of the protocol. The next 28 bits identify the organization that manages the data for this tag; the organization number is assigned by the EPCGlobal consortium. The next 24 bits are an object class, identifying the kind of product. The last 36 bits are a unique serial number for a particular tag. These last two fields are set by the organization that issued the tag. Rather like a URL, the total electronic product code number can be used as a key into a global database to uniquely identify a particular product. [29] Libraries [ edit ] RFID tags used in libraries: square book tag, round CD/DVD tag and rectangular VHS tag The design of the chip and of the antenna controls the range from which it can be read. Short range compact chips are twist tied to the shoe, or strapped to the ankle with hook-and-loop fasteners. The chips must be about 400mm from the mat, therefore giving very good temporal resolution. Alternatively, a chip plus a very large (125mm square) antenna can be incorporated into the bib number worn on the athlete's chest at a height of about 1.25m (4.10ft). [ citation needed]

RFID Lock and how does RFID lock work exactly? What is an RFID Lock and how does RFID lock work exactly?

The primary difference between RFID and NFC technology isn’t too complicated to understand. It boils down to NFC being a subgroup of RFID technology. In most cases, RFID is identified using radio waves & three primary tools: an antenna, a tag, and a reader.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. Ultra-high-frequency (UHF: 865–928MHz) (Ultra-HighFID or UHFID) tags cannot be used globally as there is no single global standard, and regulations differ from country to country. Regulatory status for using RFID in the EPC Gen 2 band (860 to 960 MHz) of the UHF spectrum" (PDF). GS1.org. 2014-10-31. Archived from the original (PDF) on 2017-11-21 . Retrieved 2015-03-23.

Williams, Christopher (2007-10-22). "Schoolkid chipping trial 'a success' ". Theregister.co.uk . Retrieved 2013-09-03. RFID or closeness cards do not need swiping movement. They use super-high frequency to make it possible for accessibility from a set short-range (consequently: closeness cards). An Active Reader Active Tag ( ARAT) system uses active tags activated with an interrogator signal from the active reader. A variation of this system could also use a Battery-Assisted Passive (BAP) tag which acts like a passive tag but has a small battery to power the tag's return reporting signal.
