Currently, Odoo supports few payment providers for its POS credit card processing. However, this does not mean that all the devices related to the payment providers will be compatible directly with Odoo. The list below provides a list of devices per payment provider that are compatible with Odoo along with a few important pointers that need to be taken into consideration before deciding on the terminal.
Note for the Community:
Please feel free to add more payment terminals that you might have tested on your end and have made work using standard functionality so that we can pool the resources together. Questions are welcome as well.
Thanks!
How about M20 Mobile Terminal?
As far as I know, that is not supported. Also the devices depend on the payment acquirer related to it so which payment acquirer will be used with the M20 terminal?
