Retrieve Failure Payment flow change to prevent double charging customers

Currently, there appears to be a critical flow issue with the handling of failure payments for POS stations that use dedicated EMV terminals like the Pax A35.

When a payment fails to make it to the POS for whatever reason the POS overlays a red ribbon over where the payment should be and a text box pops up asking users to swipe the payment. At this point the transaction stays in the Batch on the Pax device but is not visible on the copy of the batch on the POS. If the user swipes the red ribbon the payment is checked for on the Pax device and is taken care of. However if the user selects Delete the payment is deleted only on the POS side, but is left on the Pax Batch. This gives the appearance to the user that everything is taken care of and the user will go ahead and attempt to charge the customer again. However at the end of day, when the user submits the batch there are now 2 charges being submitted leading to double charging the customer which ultimately becomes chargebacks for the merchant.

Currently everything hinges on the text box which pops up when the error comes up. There are many problems with using this as the solution.

1. The only interaction users would typically have with the payment is deleting it to refund the customer. The pop up only appears once so if they cleared that message too fast, or just didn’t understand what it meant they will likely try the delete method to remove the failure payment.
2. The correct option(Retrieve) is hidden and dependent on an action, whereas the option which can lead to double charges(Delete) is plainly visible and is allowed to be done before the correct action.
   1. Should consider making sure it is not selectable at all. I don’t know what the purpose would be for allowing that to be visible when it is a double charge risk.
3. Users get fairly numb to the textboxes. I see employees just exit out of that text box as soon as it pops up. They assume it’s the same knowledge they’ve done hundreds of times to remove a payment. This is made worse by the high volume of errors that the Pax A35 produces(particularly with Tap to Pay).

Overall when it comes to the flow of the Failure payments I would like to see Linga make it easier to perform the right action and harder to perform the wrong action. I think this can be handled easily within the design of the app rather than relying on the text box.
