Issuing bank

By Wellington Costa 1 min read

Institution that issued the buyer's card and that decides, on each transaction, whether to approve or decline the purchase.

The issuing bank, or issuer, is the buyer's bank. It has the final word: the acquirer forwards the transaction, the card network routes it, and the issuer responds approved or declined in a fraction of a second.

Understanding this changes the diagnosis of a low approval rate. When the decline comes from the issuer, the problem is rarely in your checkout. It's in the transaction profile as the buyer's bank sees it: a currency unfamiliar to their history, a processing country different from the card's country, an out-of-pattern ticket, or an unrecognizable soft descriptor.

Documentation exists so a seller never learns a rule on the day it costs them. Worth reading before you need it.
