Abstract: A mobile modular biometric apparatus includes a first case to support a mobile terminal and a second case to support at least one biometric sensor. A coupler rotatably couples the first case to the second case, and a plurality of conductive lines carry signals between the mobile terminal and the at least one biometric sensor. The signals include biometric information from the biometric sensor. The coupler controls the first case and the second case to rotate between open and closed positions. The first case overlaps the second case in the closed position and has a different orientation relative to the second case in the open position.

Abstract: A mobile biometric apparatus includes a module and a first frame supporting a mobile terminal. The module includes a second frame supporting a biometric sensor having a sensing surface oriented in the same direction as a display screen of the mobile terminal. The module further includes a coupler and a connector. The coupler removably couples the first and second frames. The connector delivers powers and signals between the mobile terminal and biometric sensor. The signals include biometric information obtained by the biometric sensor. The connector may include a plug of a type configured to be inserted into the port of a smart phone, table, or another type of mobile terminal.
