Introduction

This document is the user guide for the Self-Scanning Industry Client of the GK/Retail Business Suite. The Self-Scanning Client enables a customer to scan and enter items unaided by a cashier. The Self-Scanning Client also transfers the total purchase amount of the virtual shopping basket at the end of the shopping trip to the GK/Retail OmniPOS, where the customer can pay with the usual payment methods. The customer can choose to use an industry scanning device, which is preconfigured and provided by the retailer.

The customers always know the value of their current virtual shopping basket, which saves time during checkout. The Self-Scanning Client from GK Software helps employees in retail businesses to cater for customer needs more extensively. The Self-Scanning Client increases customer throughput.

Wall Device Manager
