Fingerprint machines are biometric devices that use minutiae (distinctive features) in fingerprints to identify individuals. They are becoming increasingly popular as a way to improve security and efficiency in businesses of all sizes. Fingerprint machines offer a number of benefits over traditional methods of tracking attendance, such as time cards or punch clocks. They are more secure, as they are difficult to counterfeit. They are also more efficient, as employees can simply scan their fingerprints to clock in and out, rather than having to fumble with time cards or punch clocks.
