Excuse me, how can I keep the supermarket receipt for a longer time without words?

After buying it, you can copy it or take photos to save it. Supermarket receipts use a special kind of paper-thermal paper, and the font will disappear after a while.

Copying receipts or issuing invoices, in order to solve the problem that the handwriting of thermal paper shopping receipts is easy to fade, consumers can copy a shopping receipt and keep it as a voucher for use in case of consumption disputes. Consumers should cultivate a good sense of evidence. Of course, the best way is to let merchants issue formal invoices or shopping receipts to avoid disputes to the greatest extent.
