An electronic point-of-sale authorization device is removably attachable to an auxiliary register system for verifying the identity of a user during point-of-sale transactions. The device may include a user interface, a microprocessor coupled with a memory, displays, fingerprint and card readers, an electronic pen and a communication link. The device may further include a mechanism for pivotally oscillating the housing and a mechanism for linearly reciprocating a telescopic support rod. A user interface may be communicatively linked to the pivotally oscillating mechanism and linearly reciprocating mechanism such that the housing may pivotally oscillate about a pivot axis while the support rod telescopically reciprocates along a vertical axis respectively. In addition, the housing may be freely rotated about the pivot axis while each of the support rod and the mounting bracket remain at static positions.
