### Overview

Pay by Account Program helps Account Holding Institutions (AHIs) (for example, banks, credit unions, and digital players) accelerate the digital transformation of everyday payments by offering consumers additional payment choices using a new, robust, and secure retail payment solution.

It is designed to allow merchants to be paid in near real time through a faster payments network managed by a Designated Settlement System, and also functions as a traditional debit Mastercard transaction to be used in Mastercard's global acceptance network. Pay by Account enables consumers to use a digital account-based payment solution through an AHI's online and mobile platforms to process secure retail transactions through tokenization and dynamic cryptography. The solution allows consumers to select an eligible Consumer Account (for example, consumer deposit, prepaid, electronic money, and stored value accounts) with their AHI to make a payment to a merchant across a range of use cases including online, in-app, in-store purchases, and Automated Fuel Dispenser (AFD).
