Text from the NTA earlier...
Card Payments: Under the European Payment Services Directive (PSD2), from 13th January 2018 it is illegal to add any additional charge to customers for payment by credit or debit cards covered by this Directive, which includes Visa and Mastercard. This new law supersedes the previous arrangement for taxis where a charge of up to 5% could be added.
Details of this are also available on our website under latest news.
