## Questions & Answers

**Q: Does this reader work with NHS smart cards**
A: Yes, this card is supported. But you might need to install some NHS card reading software. You have to check that with the NHS card info.

**Q: Does it work with windows 11?**
A: Hi,
The Datasheet specifies compatibility with the following operating systems:

Windows 10/8.1/8/7/Vista/Server 2012/Server 2008R2
Windows CE (6/7) depending on hardware
Linux Debian 6.0+ / Ubuntu 11.04+/ Fedora 15+; Open SUSE 11.4+
Mac OS X; Android™

Windows 11 is not specified but I would expect readers compatible with Windows 10 to maintain this functionality into Windows 11.

**Q: Can anyone help me please...Can anyone tell me how to download the program for Linux as it doesnt do anything when plugged in**
A: It really depends what card are you trying to read. Try searching for software for your smart card type. Or check with card issuer what software to use.

**Q: is there any software to allow me to logon to windows/ Mac?**
A: It should self-install drivers when you plug it into an online computer. There was no hassle in my experience with a PC. 

I used Horizon client to read the card, because that's my organisation's policy. Just ask the IT service ay your workplace, if that applies.

The HID OMNIKEY is basically the Volkswagen of tachocard readers, solid, dependable, and not exactly thrilling, but it’ll get the job done without bursting into flames. Personally, it’s a toss-up between this and the Cherry. The Cherry only wins if you value a card reader that could double as a murder weapon. The HID, on the other hand, is lightweight, nicely built, and comes with a clever little base that keeps it steady without gluing it to your desk. Want it horizontal like an ATM? Tough luck, you’ll need to buy another base. Setup is idiot-proof and it plays nicely with all the big tacho software (yes, Tachomaster friend, it'll work just fine). For twenty quid, the value’s cracking. You really can’t go wrong, UNLESS you’re the sort of boss who underpays and overworks your drivers. In that case, skip the HID and go for the Cherry; it’s sturdier for when the mutiny begins.
