Artificial intelligence is being used to help people decide what to buy and what to eat. A new study found that customers using smart carts spent more at the supermarket than those using traditional carts. The study, which tracked over 12,000 shopping trips, showed a significant increase in spending and items purchased by smart-cart users.

Smart-cart users spent 32 percent more and bought 25 percent more items than traditional cart users. They also spent more time in the store.

Further details on the study's findings are available, including comments from the lead author, a lecturer in marketing.
