U420-4G
A standalone reader for access control and time and attendance that takes a fingerprint, a face, an EM RFID card, a PIN, or any combination of them. The 4G connection is the point: it reports from a site with no fixed line, and the integrated controller opens a door.

The other two
All three write to the same attendance record. The choice is how people identify themselves, and how many of them there are.
