Since IC card technology is coming out, it has been sustained and rapid development. Now, IC cards are widely used in electronic payments, urban transportation, attendance management, mobile telecommunications, hardware or software anti-piracy, identity, health and social insurance and other fields . IC card technology has become a required grasp of the practical technologies for the electronic information and other professional students.
The design presented to ZLG500A Mifare contactless IC card radio frequency (RF) module to read and write the SCM applications, the design includes the following elements: put forward a AT89C52 MCU to control the core, non-contact IC card Technology and electronic password lock combination of technology solutions, given the hardware and software circuit design structure, described in detail the system's hardware lines and structural elements of the design and software design elements, are given all the important Routines Flowchart. As contactless IC card operation to facilitate fast, high reliability and long life, security, good security, and anti-jamming ability, so that password lock have high security, reliability, and very high prospect.
