ViViPOS 'Club V' Loyalty Module
It's a simple application along the lines of the old fashioned 'Customer Loyalty Card'
Buy 'X' number of items and get your next one free.
Quick Access Function Keys
You could print loyalty cards with bar-codes if you wanted to,
but 'Club V' is designed to be a NO COST loyalty solution, so all you need is a bar-code scanner.
It would work without but you would have to type the bar-code each time and that would slow you down.
