The GDPR anticipates that a company may process personal data as long as one (or more) of six lawful purposes applies.1  One of those lawful purposes relates to the collection of personal data about a person as part of performing a contract with that person. 

The Article 29 Working Party – the predecessor to the European Data Protection Board – recognized that a company is processing data for the purposes of performing a contract when it “processes credit card details in order to facilitate payment” for a good or service.2  Arguably, the collection and maintenance of salary and payment details might also be based upon the legitimate interest of a merchant and a customer to the extent that an argument is made that the use of credit card information is not strictly necessary to complete a transaction (e.g., currency or a check could also presumably be used), but acceptance of credit card offers convenience to both parties.
