Thermal receipt paper fades, but the transaction record doesn't.
That receipt you kept for warranty purposes will be blank in a few years. Meanwhile, the merchant, the payment processor, and the bank all have permanent records of what you bought, when, and where. The paper is ephemeral, but the data isn't.
Stop relying on receipts for records and consider what permanent transaction logs exist about you.
