Poynt terminals are purchased through certified resellers or ISOs, and not directly via Poynt or other vendors. As such, each reseller has a unique on-boarding process and specific partners they work with, either credit card processors, apps, etc.
If you would like to change your processor, you will need to contact your reseller to initiate this process. The reseller might be able to do the switch then and there, or will have to swap your device depending on the complexity of the change.

Poynt does NOT recommend changing processors without going through your reseller, as functionality might be lost during the transition.
