If a company in China says it accepts Visa, does it accept all Visas?
Generally, credit card networks (as opposed to debit/ATM cards that may or may not have Visa/MC logos) have a rule that a merchant must accept any credit card with their logo. Visa rules for merchants in the US say it explicitly: Accept all types of valid Visa cards. Although Visa card acceptance   rules may vary based on country specific requirements or local   regulations, to offer the broadest possible range of payment options   to cardholder customers, most merchants choose to accept all   categories of Visa debit, credit, and prepaid cards.* Unfortunately the Visa site for China is in Chinese, so I can't find similar reference there. You can complain against a merchant who you think had violated Visa rules here. That said, its not a law, its a contract between the merchant processor and the Visa International organization, and merchants are known to break these rules here and there (most commonly - refusing to accept foreign cards, including in the US). Also, local laws may affect these contracts (for example, in the US it is legal to set minimum amount requirements when accepting credit cards). This only affects credit card processing, and merchants that don't accept credit cards may still accept debit cards since those work in different networks, under a different set of rules. Those who accept credit cards, are also required to accept debit cards (at least if used as credit).
