Description
Overview
This 13.56 MHz HF RFID Reader Module is a modular circuit. User needs send the reading or writing commands to the Contactless IC Card via it. This module complies with LEVEL 1 standard of EMV 2000, EMV 2010 and PBOC 2.0.It adopts a split design, uses a 50 Ohm coaxial cable to connect the outside antenna, and is used an impedance analyzer to adjust the RF circuit and the antenna to match the impedance, which can achieve very good read and write performance and very good stability. It adopts a surface mount installation form, and its ultra-small size is a major feature. It has many functions, supports a variety of international standards contactless IC cards, and supports cards from many different suppliers. The designer has classified and integrated the commands of the contactless IC card, so the commands issued by the user to the module are relatively simple, but they can complete the overall operation of various contactless IC cards.
