Co-Badged Card

A co-badged card, also called a dual-network or dual-branded card, is a payment card that supports more than one card network. Typically it combines a domestic network, which handles payments within one country, with an international network such as Visa or Mastercard, which allows use abroad and online. Each network's card acceptance mark appears on the card, and the chip holds separate applications for each.

Co-badging lets issuers offer one card that works both cheaply at home and widely abroad. It also gives merchants and, in some markets, cardholders a choice of network for each payment, which creates competition between schemes on fees. Laws in the European Union, the United States and Australia actively protect this choice. Co-badging is distinct from a co-branded card, which carries the brand of a retailer, airline or other partner alongside the issuer's brand but runs on one network.

When the card is used at a terminal, the chip presents a list of the payment applications it supports. The terminal, the merchant's acquirer or the cardholder then selects which network will route the transaction. The choice affects which interchange fee and scheme fees apply, which rules govern disputes and which network authorises and clears the payment. For online payments, the card number and routing data similarly allow the merchant's processor to choose a network, depending on local rules and technical support.

• France. Most cards combine the domestic Cartes Bancaires network with Visa or Mastercard, with domestic payments usually processed by Cartes Bancaires.
• Germany. Bank debit cards traditionally combine the domestic girocard system with an international debit brand for use abroad and online.
• Australia. Many debit cards are dual-network, combining the domestic eftpos system with Visa or Mastercard. The central bank has pressed for least-cost routing, so merchants can send contactless payments over the cheaper network.
• United States. Federal rules require debit cards to be enabled on at least two unaffiliated networks, so cards often pair Visa or Mastercard with a debit network such as those operated by processors. Merchants may choose the route.
• Other markets. Similar models exist in other countries where a domestic card scheme works alongside international brands.

In the European Union, the Interchange Fee Regulation includes specific rules on co-badging. Card schemes may not prevent issuers from putting two or more brands on the same card, and merchants are allowed to set a priority for one brand at their terminals, while cardholders can override that choice. Schemes must not use technical or contractual means to block co-badging or the merchant's choice. In the United States, the Durbin Amendment and the Federal Reserve's Regulation II prohibit exclusive network arrangements for debit cards and forbid issuers and networks from restricting merchants' ability to route transactions. The Federal Reserve later clarified that this two-network requirement applies to online payments as well as in-store ones. Australia's regulator has used policy statements and expectations rather than detailed rules to encourage dual-network issuance and routing. All these approaches aim to keep competition between networks alive, especially for debit cards.

For merchants, co-badging is valuable mainly because it allows debit routing to the network that offers the lowest cost or best approval rates. Merchants or their processors can use smart routing rules to choose a network for each transaction based on fees, success rates and the type of payment. However, choice works only if the terminal software, the acquirer and the online checkout support it; in practice some merchants have found that default settings favour the international network. Card schemes, in turn, compete for routing with pricing incentives to issuers and merchants.

Co-badging supports domestic networks, which are often cheaper and may help with local resilience and data sovereignty, while giving cardholders global reach. It promotes price competition and can lower merchants' cost of acceptance. On the other hand, it adds complexity for issuers, which must manage two network relationships and chip applications, and for merchants, which must configure routing correctly. Some domestic networks have declined over time as international schemes expanded, and European policymakers have discussed co-badging as part of efforts to strengthen European payment options. Cardholders may also not understand which network was used, which can matter for dispute rights and benefits tied to a particular brand.
