Latutude E7440 RFID reader API

Dear All,

I've bought a bunch of Latitude E7440 with the internal RFID reader. I need to write ann application which uses the Latitude RFID reader, Of course the Dell RFID driver has been installed, but is not clear what are the Windows 7 64bit API available for the Latutude RFID reader. Any help ? The best shoud be to acces to the API in VBA.

I've installed Dell Data Protection | Security Tools  Dell Data Protection package and also the NFC driver from the dell support site.

Thanks

Paolo
