QDE-620L-2 is an RS232-based contactless reader/writer which supports ISO14443, Mifare, FeliCa, ISO15693. It provides SAM and contact smart card interface.
This reader provides a useful SDK. SDK includes test program , sample source code, protocol specification and API manuals. The reader is very easy solution for adding the smart card interface on the existing system. Because the reader provides RS232 interface for connecting to a PC or any other host system, it can be used easily. In particular e-Passport and NFC market are the new target of the reader because it supports PC/SC mode, high-speed data rates on the air interface(847K), integrated RS232 interface, SAM interface as well as extended functions. The optimized bootloader enables firmware updates via USB with PCSC protocol and proprietary protocol.
Target Market : Issuing System, E-Passport System, E-Payment
System, Developing COS, Campus or Institute System
