Gatekeeper CartControl®: protecting trolleys and improving the shopping experience

Grocery retailRomaniaSecurity & Loss Prevention

About the project

Shopping trolleys are essential to customer experience and efficient grocery store operations. Keeping enough trolleys available supports shopper convenience and makes larger purchases easier.

Gatekeeper CartControl® helps retailers address trolley loss caused by unauthorised removal beyond the store perimeter.

The challenge

Trolley theft can create replacement costs, reduce availability and affect the customer experience.

  • Loss of trolleys removed from store premises.
  • Fewer trolleys available for shoppers.
  • Additional costs of replacing and managing lost trolleys.
  • Missed sales opportunities when a lack of trolleys makes larger purchases difficult.

The solution: Gatekeeper CartControl®

CartControl® protects shopping trolleys using smart locking wheels and a perimeter antenna installed around the store’s defined area. The Gatekeeper wheel receives locking or unlocking signals from the system.

When a trolley crosses the configured perimeter, the wheel can stop it from moving. Depending on the installed configuration, the trolley can return to service on re-entering the authorised zone or through the system’s authorised unlocking procedure. This approach helps prevent unauthorised removal of an important store asset.

How the system works

  1. Defining the perimeter: an antenna at the access area or in the car park defines where trolleys can be used normally.
  2. Automatic locking: when the configured boundary is crossed, the Gatekeeper wheel receives the locking signal and prevents movement outside the authorised area.
  3. Unlocking: the trolley can be unlocked on returning to the designated zone or through an authorised procedure, depending on the installed configuration.

Results and benefits

  • A stable trolley fleet: reducing losses helps maintain enough trolleys for daily operations.
  • Better availability: customers have easier access to the equipment they need for shopping.
  • Supporting sales: trolley availability removes an operational barrier to larger purchases and can support sales opportunities.
  • Operating cost control: lower losses can reduce purchases, replacements and associated management effort.

Conclusion

The implementation of Gatekeeper CartControl® in Romanian grocery retail highlights technology’s role in protecting assets and improving operations. Smart locking wheels and an electronically defined perimeter help prevent unauthorised trolley removal, maintain availability and support a better shopping experience.
