Sainsbury’s contactless and card payments went down leaving customers furious as they were unable to pay for shopping | The Sun https://buff.ly/3DPIRlq
“”They don’t tell you before you start shopping either. They like to let you fill up your trolley first so you waste your morning.”
I don’t understand why retailers don’t have a backup plan, since this sort of thing happens all the time. Ring it up as a cash transaction, take the receipt to the store manager or whoever and have them take the payment using an Android/iPhone. The till roll can be reconciled at the back end, surely?
Yes there would be a queue but there wouldn’t be abandoned carts and furious customers.
Or even just take a picture of the customer’s card and do a manual entry when the POS comes back up?
