When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. [1] Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered ...
A card reader is a data input device that reads data from a card-shaped storage medium and provides the data to a computer. Card readers can acquire data from a card via a number of methods, including: optical scanning of printed text or barcodes or holes on punched cards, electrical signals from connections made or interrupted by a card's punched holes or embedded circuitry, or electronic ...
Mobile RFID (M-RFID) are services that provide information on objects equipped with an RFID tag over a telecommunication network. [1] The reader or interrogator can be installed in a mobile device such as a mobile phone or PDA. [2] Unlike ordinary fixed RFID, mobile RFID readers are mobile, and the tags fixed, instead of the other way around.
RFID is a wireless technology supported by many different vendors for tags (also called transponders or smart cards) and readers (also called interrogators or terminals). In order to ensure global operability of the products multiple test standards have been developed.
RFID antenna used by trackside AEI readers. As of 31 December 1994, Amtech had shipped over 3.1 million tags to railways in North America. The AAR reported that over 95% of the North American rail car fleet was tagged. Over 3,000 readers have been installed by the railways in North America as of the end of 2000. Amtech was bought by TransCore.
HID Global supplies its readers and credentials for access control to Banco do Nordeste of Brasil, [16] Employers Mutual Casualty Company [17] HID Global provides network access control to the China Pacific Insurance Co. [ 18 ] and Jinwan District People's Procuratorate [ 19 ] located in Sihucheng District, Zhuhai city.
The Electronic Product Code is one of the industrial standards for global RFID usage, and a core element of the EPCglobal Network, [3] an architecture of open standards developed by the GS1 EPCglobal community. Most currently deployed EPC RFID tags comply with ISO/IEC 18000-6C for the RFID air interface standard.
Cards may be Type A and Type B, both of which communicate via radio at 13.56 MHz (RFID HF). The main differences between these types concern modulation methods, coding schemes (Part 2) and protocol initialization procedures (Part 3). Both Type A and Type B cards use the same transmission protocol (described in Part 4).
