I’ve had that done many places across the country, it’s not really a new thing. We have a brewery in our area that has a “loyalty” program where they just scan your “loyalty” card and it tracks your purchases and has your card on file. It works good, they say it is on an unconnected server, and you don’t get hit up for a tip on your bill. The owner implemented it because it saves him labor. Your card gets charged at the end of the night. It’s really a pretty easy system. The help scans your card, order, and table, then moves on. The order goes to the bar, gets filled and sent out by any other help. Same process each order. They must pay help well because the signs on the tables say tips are not encouraged, but will be pooled and split by all help. Their turnover is almost nonexistent.
