Using Store & Forward

  • CommBank’s Store & Forward feature means you can keep taking card payments with your EFTPOS terminals, even when your terminal is unable to connect to the bank
  • Store up to 100 transactions if your terminal’s connection to the bank drops out
  • Once you’re reconnected, these transactions automatically get forwarded to the bank for processing
  • Make sure you keep all your offline receipts as back-up
