I am developing a system to register visitors. The visitors wear a wristband containing an NFC tag.
In order to read the tag, I am currently using a cheap Samsung Android phone, with built in NFC reader, which costs around GBP 60 / Eur 77 / USD 87.
I am considering replacing the phone with a Raspberry Pi and am thinking about an NFC reader.
I could use a shield, and am open to recommendations, but it always seems uncomfortable tapping a phone to someone's wrist and I doubt that tapping a Pi would feel any more comfortable (especially if the Pi is wired for mains power).
Is there a cheap wand, or other device, which can be connected to the Pi for a less awkward scan of the wristband?
Budget will play a role in this, but I am not yet sure how much of a role (sorry).
