The figures confirm it: shrinkage in Spain continues to rise, driven primarily by theft on the shop floor. Organised gangs, repeat offenders and opportunistic shoplifters coexist within the same environment, taking advantage of vulnerable points. In this context, CartControl and Purchek form the cornerstone of a critical security strategy.
How CartControl and Purchek help reduce theft
The data is revealing: according to the latest reports, external theft accounts for more than 50% of shrinkage in Spanish supermarkets, with incidents concentrated on the shop floor and at self-checkout areas. Prevention is no longer optional; it is an essential part of protecting assets, employees and customers.
News of organised theft, losses amounting to millions of euros and increasing levels of aggression in certain stores is becoming more frequent across the country. For many businesses, strengthening protection is now just as important as increasing sales.
At Carttec, we have developed two systems designed to act precisely on the most sensitive areas of the supermarket environment:
- CartControl: an advanced system that protects shopping trolleys by automatically locking the wheels when they attempt to leave the designated perimeter. Its SmartWheel technology ensures that trolleys remain within the sales area, preventing losses and improving availability for customers.
- Purchek: an integrated security system built into the trolley that locks the wheels if a customer attempts to exit without passing through the checkout. It also activates a configurable alarm to alert store staff and, through its integrated camera, captures images of the attempted theft. The process remains discreet, ensuring security without disrupting the shopping experience for other customers.
In short: CartControl prevents trolley theft, and Purchek prevents the theft of goods inside the trolley.
Beyond their core functions, these systems also enable the collection and analysis of valuable data, such as behavioural patterns, peak risk periods and the most vulnerable areas within the store. Information is power and, in this case, a strategic tool for improving staff allocation and optimising security resources.
Transforming supermarket security
Implementing advanced retail security systems helps to minimise financial losses while reinforcing customer confidence, as shoppers perceive a safer and better organised environment. It also supports employees, allowing them to work more efficiently and with greater peace of mind.
Introducing solutions such as CartControl and Purchek reduces theft-related losses and optimises both human and technological resources in-store. At the same time, these systems increase deterrence against organised groups and repeat offenders, while enhancing the overall shopping experience and strengthening perceptions of safety.
