The iSHARE Trust Framework aims to support multiple interaction models, of which Machine to Machine (M2M) is one. M2M interaction can be characterised as communication between machines, without interference by a human. In contemporary data communication there is a heavy reliance on M2M interaction. 

Example:

• Every day, the ERP system (machine) of party A requests a status update from the ERP system (machine) of party B. Party B's ERP system automatically responds with the requested status update. No humans are needed to interfere. 

This example is detailed under use cases.

The opposite of the M2M interaction model is the Human to Machine interaction model.
