I’ve added support for the Halo Scanner to SiRFIDaL, thanks to the help of the manufacturer.
If you think this is cool and you like how they treat our little community, drop them a line next time you order a Halo Scanner.
Of course, video proof is needed 
This is me locking / unlocking my session with my xBT:
Incidentally, I recently did a major code cleanup of SiRFIDaL. The new codebase is quite a bit more efficient if you have a lot of readers connected, and more importantly, the settings make a lot more sense.
Also, as a recap, here is the list of devices that SiRFIDaL now supports - quite a bit more than what it started with by now:
- PC/SC readers (ACR122U and others)
- Serial readers
- Halo Scanner
- HID readers (aka keyboard wedges, e.g. KBR1)
- NFC-enabled Android devices (e.g. old cellphone you want to turn into a tabletop reader)
- Proxmark3
- Chameleon Mini / Tiny
- Digital Logic uFR, uFR Nano, uFR Nano Online
- Ethernet readers that push data to HTTP servers
- Ethernet readers that serve up data as a TCP server
