Shift4

Before connection can be established with the PED, a pre-configuration is needed using UTG service (Universal Transaction Gateway). An Api Key must be generated with details about the merchant and the setup. Note: Contact Shift4 for more details.

Communication is session-based to keep the connection alive, if further verification is needed from the POS.
