One of the most important aspects of the MFS environment is mobile payments to businesses. There are many ways a consumer, or a business as a consumer, can make a payment to a merchant. ISO 12812 provides a comprehensive standard for using the mechanisms involved in mobilizing the transfer of funds regardless of who is involved in the process. This document is intended to be used by potential implementers of mobile retail payment solutions, while ISO 12812-4 is intended for potential implementers of solutions for mobile payments to persons.
NOTE ISO 12812‑1:2017, 5.4 explains the differences in the use of these terms. As such, the ISO 12812 (all parts) seeks to support all possible technologies and is not designed to highlight or endorse specific technologies in the competitive marketplace.
Although this document deals with mobile payments made by a consumer or a business acting as a consumer, which transactions are subject to a variety of consumer protection requirements, in terms of the relationship to the MFSP, the consumer (or business) is the customer of the MFSP. Nevertheless, this document will use the term consumer.
