The Interchange Fee Regulation (IFR) was introduced in June 2015 to curb charges and require card payment providers to be more transparent.
But while IFR capped bank and merchant interchange fees at 0.2% for debit cards and 0.3% for credit cards, Abta says other fees have been increased or introduced – wiping out savings to retailers.
The association’s call for evidence comes after its concerns about the cost of card payments were recognised by economic secretary to the Treasury John Glen.
Glen said the Treasury would continue to monitor the effect of IFR, adding the Payment Services Regulator (PSR) had requested Abta members report any breaches.
