Are merchants permitted to establish minimum or maximum transaction amounts for payment cards? Are they permitted to charge me extra for using my credit or debit cards?
No. Merchants are not allowed to establish minimum or maximum transaction amounts or impose a surcharge for payment cards unless the local law expressly requires a merchant be permitted to impose a surcharge. This is against the policy of international card companies. If you encounter a merchant that does impose a minimum or a surcharge, you can report this to your credit card issuer which may choose to report the merchant to its acquiring bank.
