Software Installation

Prepare a factory-installed M425A terminal for a site.

Software Installation

EVPay arrives pre-installed on the M425A. A setup visit is still required before the terminal can process payments.

A Verifone technician or designated setup contact completes the following steps.

1

Confirm the operating system

Confirm the Android version is approved for the production site. Apply any required OS update.

2

Configure the network

Configure the IP address, gateway, and DNS. Connect the terminal to Commander through Wi-Fi or Ethernet.

3

Load the identity certificate

Install the terminal identity certificate. This certificate identifies the terminal to Verifone services.

4

Load encryption keys

Load debit PIN encryption keys securely using TR-34. Keys are unique to each terminal.

5

Configure VHQ

Point the terminal to its correct VHQ instance. Petroleum terminals normally use PetroHome VHQ.

6

Apply Commander configuration

Apply payment settings, prompts, and fleet parameters through Commander Configuration Client.

7

Complete test transactions

Test chip, contactless, magnetic-stripe, and debit PIN transactions before going live.

Replacement terminals require the full setup process. They do not inherit certificates, keys, or settings from the replaced terminal.

Software updates

M425A terminals receive approved EVPay and configuration updates through VHQ. Updates normally run during scheduled maintenance windows.

• The terminal waits until no transaction is active.
• It restarts automatically after the update.
• Commander can also trigger an approved on-demand update.

Do not disconnect power while an update is running.
