Caller Identification Through Acoustic Signal

CCard from ComCard is a plastic card the size of a credit card which enables the quick identification of a person calling on the telephone. It sends out sender-specific numbers encoded and transmitted via telephone as a succession of acoustic signals. This customer or membership number is decoded online by a data processing system installed in a service or call centre. In this way the address and all the person's details are at disposal directly after receiving the acoustic signal. All existing telephone systems are able to transmit this acoustic code.
