Can any NFC RFID reader/writer be used with a Digital Logic SDK?

Can any NFC RFID reader/writer be used with a Digital Logic SDK? Digital Logic Ltd. is an NFC RFID development tools manufacturer. We provide software support for our hardware only. All the SDK projects have been developed for implementation with our µFR Series (including Base HD) and µFR Online Series of reader/writer devices. They rely on our customized uFR library and cannot be used with third-party hardware. If you are interested in developing your system based on some of our free SDK projects, you may consider choosing some of the µFR hardware models available at  https://webshop.d-logic.com/products/nfc-rfid-reader-writer/ufr-series-dev-tools-with-sdk.html. All these devices are mutually compliant, so work with our SDKs, can be combined and merged into a single system, and you can also switch out one model for another without changing your code. Please feel free to contact us for any further details.

 Is there any NFC RFID tool that can register RFID cards on a computer and its data on a server?
