In each step of the enrollment the template gets refined so to speak.. after the 3 captures at enrollment you get one template. At verify/identify the finger is captured once, some kind of match rating is calculated and then matched (match rating > some threshold)
against a specific template (verify) or the database (identify).
You can fill the sensor DB with your stored templates and use identify.. or if you know which template should match just validate against a single template.
Look at the datasheets i linked. The functions are Verify/Identify/VerifyTemplate/IdentifyTemplate
-- Edit --
@allObjects This sensor is quite finicky at enrollment.. you have to press and release your finger.. and if i press the finger more then a tiny bit a different way the enrollment fails. Switching fingers fails too.
