The document discusses upcoming changes to card processing fees for merchants in the UK. Starting in March 2015, interchange fees that merchants pay to accept debit and credit cards will be capped under new EU regulations. This aims to lower the fees from their current rates of 0.8% for credit cards and 8p for debit cards to 0.3% and 0.2%, respectively. However, while some merchants may see lower fees, others may see increases of up to 30% as payment suppliers adjust their rates in response to the regulatory changes. It is advised that merchants understand how the changes may impact their individual processing costs.
