Merchant processing or account is a kind of bank account that allows businesses to acknowledge payments by check cards, typically debit or bank cards. A merchant processing is established under an understanding between an acceptor and a merchant acquiring bank with the settlement of check card transactions. Now and again a payment model, independent sales corporation, or member service provider is also a celebration to the business agreement. Whether a merchant enters in a merchant agreement directly with the acquiring bank, the agreement contractually binds the merchant to observe the operating regulations established from the card associations.
