A micro market is a small, self-contained store in a location without an employee to monitor it. It’s comprised of freestanding storage, such as shelves, that hold a product and a checkout system installed nearby. This means that there is no machine that vends the product, but the system is autonomous like a vending machine. Most micro markets are honor-system based and thus must be in a secure location, but there are new technologies such as pressure-sensitive shelves that record when product is taken off them. For a price, these technologies give vendors the option to use a more secure vending system.
