Abstract
A mother and infant matching and security system is disclosed. The mother and infant matching and security system comprises a first tag unit adapted to be secured to an infant. The first tag unit is operable to transmit a first signal having a low frequency and a second signal having a very high frequency. The mother and infant matching and security system also comprises a second tag unit adapted to be secured to a mother of the infant. The second tag unit has a radio communication link with the first tag unit. The mother and infant matching and security system further comprises a communications protocol used by the first tag unit to communicate via the radio communications link with the second tag unit. A match of the first tag unit and second tag unit is identified by both an audio indicator and a visual indicator on at least one of the first tag unit and the second tag unit.
