SwipeSimple Mobile and Terminal require a specific Merchant Account to be selected to allow for processing in SwipeSimple. Merchants with more than one Merchant Account boarded to their account need to be sure the correct Merchant Account is selected in settings. If the wrong device is selected, an error message may appear that says:
Unfortunately the selected Merchant Account can't process transactions. Please choose another one in Settings > Merchant Account.
To resolve this error message, tap the menu button in the upper left hand corner to open the sidebar menu. Choose Settings and tap on Merchant Accounts. The current selected Merchant Account will have a checkmark. Select the correct Merchant Account associated with your mobile or terminal device and the issue should be resolved.
If the error persists or you are unable to change to a Merchant Account Device in settings, it's best to close the SwipeSimple application and reopen it. To close SwipeSimple on a PAX terminal, tap the Square Button on the bottom left, and then tap the X to dismiss the application. Reopen SwipeSimple and repeat the above steps to select a different Merchant Account.
