Sainsbury's trial of till free shopping means wine cannot be sold

Trials of till-free stores by Sainsbury's has meant the wine and other alcoholic drinks can not be age verified and so cannot be sold legally. Sainsbury's has got around this by removing all alcohol from the store.

The concept of shop and walk where cameras monitor what you have purchased and charge you automatically has been tried by a number of retailers, including Amazon. There are a number of potential solutions such as RFID tags (currently used in the UK over the lids of high value spirits) but they require the customer to go to a sales representative to have the cap removed and this slows down the sales process, defeating the object of going till-free.
