These fingerprint scanners from ADH Tech use UART to communicate to another microcontroller (e.g. Arduino) or single board computer (e.g. Raspberry Pi). The scanners have their own onboard memory storage for remembering fingerprints, which means you can move the scanner between projects, and it will still retain its database! To connect to the scanner, you will need a 4-pin JST SH connector. Note that the UART relies on 3.3V TTL signalling, so you will need to use a 3.3V microcontroller/computer or a logic level converter.
