Self Checkout

I can't believe yall thiefs are ruing self check out.. I guess it wass good while it lasted.

At work (plant Warehouse) we tag all items with an RFID tag (3x1 inch labels, but they make them much smaller). If they pass back through the door with 10 items, it picks those items up.
Seems like a option to put these tags on items over a certain dollar amount and if you do not scan this item, it knows you didn't and puts up a red flag. Now, just like when self checkout started it was a pain with ITEM NOT BAGGED, but eventually, it got better. i rarely have issues with self check out.
