An existing Internet standard, already commonly used in Internet shopping, aiming to produce common methods for transferring transaction information from the client wallet to the server application. See www.ecml.org/ for an overview.
- It can be used whenever applications need a common method for transferring e.g. address information, and not just transferring credit-card information - It is a structure, not a protocol - ECML is security mechanism-independent, and can/will be integrated to other transaction protocols and security elements when available
