Shopping trolley manufacturer Wanzl has been working on a smart solution for years. The so-called smart trolley is supposed to make it possible to unlock shopping carts digitally – with a smartphone or smartwatch.
To unlock, customers have to download the app of the respective supermarket or discounter to their smartphone. In a next step, only the mobile phone has to be held over the digital deposit lock, and the shopping cart is then unlocked via NFC or Bluetooth. This would make the conventional coin superfluous.
