Abstract
This invention provides a base unit for charging a handheld ID reader in which the charging contacts are mounted on a contact holder that is biased rearwardly during insertion of the reader, and thereafter snaps back in place and locks the reader after the reader has been pushed into a fully seated position in a well of the base unit. This lock is maintained between shoulders on the holder and corresponding locking tabs on the bottom face of the reader. The locking tabs are conductive, and provide two additional electrical contacts that engage contact pads on the reader bottom face. Each of the power and ground signals are connected over at least two electrical contacts between reader and base station, increasing reliability, especially when the reader is not in its fully seated position. An indicator LED is integrated in the base station enclosure near the charging contacts.
