Shopping carts are a utilitarian asset meant to help haul goods you intend to purchase to the checkout lanes. Walmart, it seems, believes carts should be capable of far more.
The big box retailer filed a patent earlier this year for a connected shopping cart with a biometric feedback handle. As per the patent, the cart’s handle could measure a shopper’s heart rate, temperature, their grip strength on the handle, their oxygen saturation, how long it has been since they last grabbed the cart’s handle and even the cart’s speed.
