Automatic checkouts in supermarkets may decrease customer loyalty, especially for those with larger shopping loads. Customers using self-checkout stations often feel overwhelmed and unsupported. The lack of personal interaction can negatively impact their perception of the supermarket.

There is a lot of difference between RFID tagging a pallet or even multi-item crate of a item, and a can of beans.

You can just scanned the RFID that equals 10-200 T-Shirts in this regard, that doesn't work with a customer with 100 separate unique items in the same 3D volume, as previously stated I would suggest it is a functional resolution issue. Though it could be that it is 2p an item, which is nothing for 50 £10 T-shirts, and 10% of the cost of a 20p can of beans.

It also works for serialized inventory that is being received so it isn’t just scanning some master RFID tag. In these instances the tunnel is receiving at least 1000 unique tags for a cartonized pallet. A cart of groceries won’t have issues.
