If you see “PED Tamper” appear on your Shift4 terminal, there are actions you need to take to be able to accept payments again. PED Tamper is a security lockout of the system, for the protection of your customers and your business. If this appears, it means your Shift4 terminal needs to be replaced – contact Shift4 to action this.
PED Tampers happen from the terminal being dropped or damaged, suffering water damage, power surges or incorrect voltage being applied to the terminal.
