-The Telium protocol is used by Ingenico and Sagem payment terminals. It is based on the Concert protocol, so it can probably work with payment terminals from other brands. It has been tested a an Ingenico EFTSmart4S terminal with Telim Manager version 37784503. The protocol E is implemented (we may implement the protocol E+ in the future).

This module implements the protocol E+ (and not the protocol E), so it requires a Telium Manager version 37783600 or superior. To get the version of the Telium Manager, press F > 0-TELIUM MANAGER > 2-Consultation > 4-Configuration > 2-Software > 1-TERMINAL > On Display > Telium Manager and then read the field *M20S*.
