@Edent you need something that works with pcsclite. These things use a chipset made by NXP, and usually the internal are designed by 2 companies: HiD or ACS.
The ACS ACR122u has been the staple for the last 10+ years.
For HiD, look at the 'omnikey' line (I don't know what their latest thing is).
Both are available through the usual robbers (the one is 'zon, digi-key, RS)
