How to enable Westpac Pay At Table

Supported on Abacus POS 2.8.100 and later.

You can have 1 Westpac Pay@Table terminal per POS, which can be either the Master or Slave. Every terminal must connect to its own POS.

When your Westpac payment terminal and Abacus POS are connected to each other, toggle on Pay At Table on the top right corner of the Simple Payments Integration page. Your Westpac terminal will then say Pay At Table.

With Pay At Table enabled, a waiter will be able to select which table they would like to initiate payment for, using just their payment terminal without the POS.

  5. When the unpairing has been completed, the screen will display "Terminal unpaired".

  6. The screen will then display "Pair with POS". This means your Presto Smart VX 690 is now in standalone mode.
