SenseFP Series
Compare SenseFP M1 and M2 fingerprint-attendance listings, including the separate supplier-listed M2 configuration. These models do not acquire facial recognition simply because a related SenseFace product has it.
Compare the required identification workflow
Review SenseFP M1 and SenseFP M2 against the required fingerprint, card and password workflow. For M2, match standard 125 kHz ID credentials or the optional IC configuration to the actual cards; card shape alone is not a compatibility check.
Check wireless and battery options
M2's parameter table lists Wi-Fi and backup battery as optional despite broader wireless wording in the family overview. Specify the exact option and software/protocol arrangement. The separate supplier-listed record still needs its hardware and firmware distinction resolved before it can be treated as a different technical configuration.
