First of all, tokenization must be enabled in System2 table

Note:  There's a special setting that must be setup on processor side.  This should be there already for most customers and ones started after 1/1/2022.

Tokenization does the following:

At tab start, when swiping the card to get the name, the card is also authorized for $0 in the background.

Note:  There is no way to tell how much credit customer has.  So still possible to decline later for insufficient funds

Within a few seconds, a screen should pop up (that disappears within a few secs) showing green (approved) or Red (declined)

If declined, a slip will also print out.  Server should do something at this moment, as they'll know that the card will not be good for any charges

Assuming card is good, than a little diamond ♦ will show next to the tab on the tab selection screen.   That shows that the tab has a card authorized successfully to it.

At close out - simple procedure - when a tab is closed out and credit selected system will prompt - Close to Card On File?  If 'Yes' is selected, previosuly authorized card will now be ran for the full tab amount.   If 'No' is selected, then any other way of payment can now be taken as was always available.
