Java App integration with Desfire Ev2 authorization, read and write

yip — Mon, 10 Mar 2025 13:43:26 GMT

I am a Java APP developer, Recently I need to integrate our OA system with Desfire Ev2 card to identity our employees, I currently have 3 desfire ev2 2k MOA4 card, and a ACR122U-A9 card reader, but I am a newbie about card development.

So my question is can this ACR122U-A9 card reader handle the work of authentication, read and write support ?, and do you guys provide the free java SDK to support our developments?

If I still need other hardware or software to do my job, what's it and where do I get it?

Hello, my name is Fabian, I've been assigned to support your case.

Thank you for your interest in our products.

Since this NFC Reader support PC/SC integration it can be used as a DESFire reader. Nevertheless, I have to strongly recommend to please check with the Reader manufacturers for possible SDKs or integrations using this reader.

We do have a .NET API for PC/SC but, will require to sign an NDA. In case you company is legally registered, we could provide an NDA to sign. But first, please take a look at the following FAQ.
