Do they hold a unique token though? Here in the UK, I've definitely gotten "loyalty" offers printed with my receipt even though I've only ever used my debit car

- Nursie 12y agoDepending on the system they can still get an account/card number. They shouldn't be storing it but... They can certainly get cardholder names and that sort of thing though. Maybe they've figured out a way to generate a unique token based only on non-secure data.
