Walmart Wants Its Trolleys to Know Your Heart

By CBR Staff Writer

Walmart’s string of unusual patent applications continues: fresh from filing six patent applications to create an automous fleet of robot bees, the US-based retail behemoth is now seeking to develop trolleys with biometric handles that can track customer heart rate, temperature and stress levels.

The system would “sleep” and be reactivated when a trolley starts moving, the patent application shows – with anomalies in biometric information alerting store staff so they can check on the person associated with that data.

The system would alert staff to customers in distress and “help improve their shopping experience” the company said.

Another application might be to highlight potential shoplifting alerts to security staff.

Walmart says it loses up to a staggering $4 billion every year from theft.

In 2015 Greg Foran, head of the retailer’s US operations, told a media briefing that he saw an opportunity to boost margins by putting a dent in the problem, saying it typically represents 1 percent for any retailer’s sales.

“One percent of $300 billion [Walmart’s revenues in 2015] is quite a lot of money. If you can save 10 basis points of it – boy I’ll take it every day of the week and put it into lower prices for customers,” Foran told Reuters after the briefing.

Other recent Walmart patents filings include a patent that uses satellite imagery to optimise carpark use and a patent that would see hundreds of sensors placed around its stores that link with customers’ phones for “dynamically transmitting alerts” after recognising items that may be of interest to that customer.

Last week, it also filed a patent for a “distributed blockchain storage system” for data backup and authentication.
