Test your terminal
Before your first transaction, test your terminal to make sure it's working properly and you're able to accept American Express® Cards.
- Choose "Sale" key on your terminal, or follow the procedures for a keyed manual transaction.
- Key in Card number 373953312381006, then enter expiration 12/XX (last two digits of current year).
- If terminal prompts for additional info, press "Enter/Send" or enter "0000" to bypass.
- When the terminal displays Decline response, this indicates a successful test transaction! Your terminal is now validated to accept American Express Cards.
*If Decline is not received, please contact your POS terminal provider to troubleshoot the issue.
