POS session timeouts

If the POS device experiences a session timeout (normally caused by five minutes of inactivity) in the middle of a payment workflow, the payment is completed to the extent that it is possible. The POS app submits the payment for authorization (as a background job) if it has not yet been submitted, and skips all remaining steps of the payment workflow. For example, the POS app will not prompt for an emailed receipt or rewards sign-up.

After handling a POS session timeout, the POS app will leave the check as though the payment had been completed normally. The check state is open, paid, or closed, depending on whether your restaurant has digital receipts enabled and/or whether the payment was for the full outstanding balance of the check.
