Payment Apps

The two payment apps need install to terminal firstly.

• PayWizard_Demo_V2.1.9_2601061.apk
• OPC_V2.3.2-global-release.apk

Local Integration(No need develop POS APP)

Suitable for scenarios where no application development on the POS terminal is needed. Instead, the Vendor Machine communicates directly with the OPC. In this case, communication between the POS terminal and the Vendor Machine supports serial port, MDB (Multi-Drop Bus), and Socket protocols.

Internal Integration(develop POS APP)

It is suitable for developing normal applications on the terminal. It can call the AIDL interface provided by the OPC application to do different transaction. It communicate with the Vendor Machine.

Best practice for payment in D22(D3)/Q3(Q2)

• Install the new accessory agent on D22(D3)/Q3(Q2)
• Install initconnectionmode on D22/Q3, configure master and slave. This step is usually pre-initialized at the factory and does not require further configuration by the customer.
• Install OPC on D22/Q3
• Set OPC to DEFAULT on D22, and set the payment packet name to com.wizarpos.opc
• Set OPC to USB ACCESSORY on Q3, and set the payment packet name to com.wizarpos.paywizard.demo
