OMNIKEY 5421 reader software

I need a programmer to write a windows based software to read a NFC CARD, then forward the CARD info into/onto a website. We are looking forward to getting ideas for the programming language, but a stand alone technology is required.


- PC computer

- Windows 10 x64

- OMNIKEY 5421 WINDOWS driver is installed on device!

- Card reader is OMNIKEY 5421, connected to an USB port

- The program could run as a background process, so graphic interface is not needed

- Computer is located behind a router with internet connection.


- The program needs to have a config file:

- Debug mode 1-ON 0-OFF

- API key: To protect against hacking, the software needs to send this code for each transaction

- Log folder to save each read for future debug. For example: c:\nfcread

Website address: for example: [url removed, login to view]

- Information which the program will send to the website:

- Card tag

- Read date-time

- Card status: 1 – CARD_OK 2-CARD_EMPTY 3- CARD_BROKEN (program needs to detect wrong card!)

- API key

- SERVER side process requires POST method, fields listed below:

- cardtag

- datetime

- card_status

- apikey

Communication with the programmer will be done exclusively in English!

Testing will be via e-mail, GMAIL chat, VIBER, possibly with remote access.
