The big four transaction networks for credit cards in the US are MC, Visa, Discover and Amex. There is little competition beyond that.
As for interbank/debit networks, there are a bunch of them. Some networks, like MoneyPass, offer fee-free transactions. Some debit networks are owned by credit networks. (Star is owned by Visa, Maestro by MC and Pulse by Discover.)
: "In the U.S., EFTPOS is universally referred to simply as debit. The same interbank networks that operate the ATM network also operate the POS network. Most interbank networks, such as Pulse, NYCE, MAC, Tyme, SHAZAM, STAR, and so on, are regional and do not overlap, however, most ATM/POS networks have agreements to accept each other's cards. This means that cards issued by one network will typically work anywhere they accept ATM/POS cards for payment. For example, a NYCE card will work at a Pulse POS terminal or ATM, and vice versa. Many debit cards in the United States are issued with a Visa, MasterCard or American Express logo allowing use of their signature-based networks."
So even though there quite a few networks, I've never had an issue using any of my debit cards anywhere.
