Learn how you can configure your card readers to work with the Toast Tap™.
If you have two screens on your terminal—most commonly referred to as a guest-facing display or Toast Flex for Guest—you can have one or two card readers with the Toast Tap™! Check out the article below to learn how this works.
You can configure a card reader to have the Guest Pay payment option with or without a guest-facing display and without needing a separate mag-strip reader.
To configure a single card reader, use the following steps:
If a single card reader is enabled, and its Payment Option setting from the Device Setup on the Toast POS app is set to Guest Pay, you can add funds to gift cards, activate gift cards, and redeem them.
Note: If you use a guest pay reader, you no longer see the Guest Pay button on the payment selection screen. The Guest Pay and Credit buttons have been consolidated into a single Card button. Manual card key entry is still available on the restaurant employee-facing payment terminal.
To configure both card readers, use the following steps:
After taking a guest's order and selecting Pay, you'll see a button for Card, (similar to the option for Cash or Gift Card). Once selected, the screen will prompt your guest with instructions to complete the payment. This will ensure that the order information is entered in entirely before the guest inputs their payment and eliminates early payments on the reader.
Note: If you use a guest pay reader, you no longer see the Guest Pay button on the payment selection screen. The Guest Pay and Credit buttons have been consolidated into a single Card button. Manual card key entry is still available on the restaurant employee-facing payment terminal.
It's important to note your Toast Tap™can only be paired up with a swipe-only reader (also known as an MSR reader). All other card readers cannot be used with the Toast Tap.
You may have your reader set to the wrong Pay setting — see .
If you only have the Toast Tap™ (On-Counter), it should be set to Employee Pay. We recognize this can be confusing if you're using it facing the guest. The Toast Tap™ (On-Counter) can only be set to Guest Pay when you have a Guest-Facing Display or Toast Flex for Guest.
No, you can never have an eDynamo (chip reader) and Toast Tap™ connected at the same time. If you have a secondary display on your terminal, you can keep an MSR card reader - the type of reader that only takes swipe payments - adhered to the employee-facing terminal. Your new Toast Tap™ will be set to Guest Pay.
