OCPI 2.2.1 is a major step forward. Nevertheless, the community is already looking ahead, because developments in this field are progressing rapidly. Responding to these developments remains important. OCPI continues to evolve.

To support CPOs with payment terminals that are not directly connected to and part of the charge station, e.g. at charge squares and situation with POS terminal in a shop, the EVRoaming foundation developed (with great support of Chargepoint) the Direct Payment module that can work together with OCPI v.2.2.1.
