Home telephones are being used to conduct business transactions with banks and stores. As part of these transactions, personal identification numbers, memorized by account holders, must be communicated in order that the bank or store can verify that the caller is the authorized owner of the account against which the transaction is to be posted. Because telephone lines can be tapped by unauthorized listeners, the communication of personal identification numbers is a security risk.
