It's similar to the "SmartECart" luggage cart kiosks you may have seen at airports. Sliding a cart in locks it in place on a set of rails, depositing the money releases a mechanical catch on the end, allowing you to pull one cart out.

The usual European shopping cart system works with a coin deposit, chains and mechanical locks on each cart, as described in several other comments.
