Last month, the Department of Trade and Industry (DTI) issued Administrative Order No. 10 (series of 2006), which prohibits, among others, the imposition of a surcharge, extra charge or additional charge in the use of credit cards, automated teller machine (ATM) cards and debit cards for payment of purchases of consumer products or services. In other words, stores cannot impose any extra charges on top of the cash price for purchases of goods or services paid via credit card. Violators face a penalty of imprisonment of up to six months. Here’s the full text of Administrative Order No. 10. It takes effect 15 days from publication.
