Card network

Network that connects the issuing bank and the acquirer, sets the transaction rules, and arbitrates disputes, such as Visa, Mastercard, Amex, and Elo.

The card network is the rail the transaction travels on. It doesn't hold the money or approve the purchase: it connects the acquirer to the issuing bank, sets the rulebook both sides follow, and arbitrates what happens when the buyer disputes a charge.

For sellers, what matters most is that the chargeback rules, response deadlines, and tolerated limits are written by the card network. Blowing past those limits doesn't trigger a fine from the platform, it triggers enrollment in the network's own monitoring program.

Buying from another country should not be harder than buying around the corner. Every step described here exists because the question already reached support, more than once.
