Abstract: Near field, communication is being used for many days today applications like e-passports, ticketing system, access control, loyalty cards, payments etc. Passive proximity integrated circuit card and proximity coupling device are used with the principle of inductive coupling. This is a wireless communication with the carrier frequency of 13.56MHz within the scope of 10cm. An FPGA platform is implemented to perform the digital system validation. Validation is performed to make sure that it is in compliance with ISO/IEC 14443 protocol with Type A communication. Some of the functional Test methods used are from ISO/IEC 10373 – Part 6 protocol. The validation is performed for multiple process corners, all protocol commands, and antenna classes varying from class 1 till class 6, baud rate up to 848kbps, extreme temperature conditions, and multiple iterations for lowest achievable field strength. The following is performed to ensure the best fit for the operating field, data rate and chip area.
