Summary:
The performance characteristics of the Tag and Reader devices may vary drastically due to application factors as well as the particulars of the RF air interface (frequency, modulation, inventory algorithm, etc.). Of key concern is the matching of the various performance characteristics to the user application. Additionally, in an open environment users of RFID technology demand multiple sources fir the devices from technology providers. A key challenge is a method of evaluating the differences between various technology providers’ products in a consistent and equitable manner. In this literature specifies the Tag performance metrics and producers for measuring them. Tags are passive-backscatter devices and operate within an Interrogator-talks-first, RFID system operating in the 13.56MHz frequency range. The system comprises Readers-also known as Interrogators, and Tag-also known as Labels. The active component of a Tag is the Tag IC which determines all of the functional properties of the Tag as well as many of its performance parameters. The following standards contain provisions which, through reference in this text, constitute provisions of the part of ISO/IEC 14443. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO/IEC 14443 are encouraged to investigate the possibility of applying the most recent editions of the standards listed below. ISO and IEC maintain registers of currently valid International Standards [1-5]. (a).ISO/IEC14443,Identification cards-contactless integrated circuit(s) cards - Proximity cards. (b).ISO/IEC 10373, Identification cards - Test methods. (c).ISO/IEC 7816-2, Identification cards -Integrated circuit(s) cards with contacts - Part2: Dimensions and location of the contacts. Various air interface modulation and coding schemes are permitted by the Protocol [1]. The measurement methods of power and bi-directional communication between Reader and Tag are presented as below section.
