Contactless payments exceeding this sum require entering a PIN code.

The contactless MasterCard Standard credit cards by UBB also cover all standard payment methods, as well as cash withdrawal. You may use them when paying in shops, restaurants, petrol stations and numerous other sites, free of charge in both Bulgaria, as well as abroad.
