Autovon 16-button Card (not shown)
Looks like cards on the top row, but is wider to accommodate
an additional row of holes.
All use a 2 of 8 code: 2 punches in a column for each digit. The dialer stops after the last punched digit.
A punch in the "STOP" row tells the dialer to stop. Pressing START continues dialing from the same card. This is useful if an access code is needed to secure an outside line, or between an account code and password, etc.
Once punched, the card is a read-only storage device.
