Chip and Sing Cards    (April Fool's Day - 2006)

The London Times reported that "Britain's banks are developing a system of credit card security that uses the voice's tonal range. Rather than needing to recall a PIN, you will need to remember a line of a song... Optical scans are too fallible, and standard voice recognition too easy to mimic electronically. But no two people sing the same way. Tills and cash dispensers are to have microphones."
