US based company Three Square Market is currently piloting its self-checkout micromarkets at three high schools in Minnesota as a cost-cutting approach to the traditional school lunch.
The micromarkets are run by a vending operator who has a commissary that supplies the packaged cold meals. Each student helps themselves to one of three choices of cold meals that meet nutritional guidelines from a refrigerated cooler that replaces the lunch line. The meals are barcoded and stocked by the operator. The student then scans the meal at the kiosk and pays by cash or card by using a biometric thumbprint reader or by punching in the identification code for their school account.
The kiosks can be programmed to give parents the ability to track what their children eat. Parents can also restrict their children from buying certain foods if they have allergies or health conditions such as diabetes.
