The company, which has multiple roles in the payments business as a card accepting merchant, independent sales organisation and payment facilitator, alleges that it has incurred billions of dollars in costs over a 17-year period as a result of the card networks' pricing. The suit, which is seeking unspecified damages, claims that the Visa and Mastercard have deliberately skirted around Durbin interchange caps and also operated a cartel through their honour all cards rules, which requires merchants to accept all network-branded cards rather than just one of their choice. Visa and Mastercard have yet to comment on the allegations.
