The security barrier comprises a mechanical enclosure that surrounds, and restricts access to, items within the vending machine. The items enclosed in the vending machine inside the security barrier include a product, a currency acceptor, and a currency within the currency acceptor. Mechanical access through the security barrier is provided through a locked access port. The vending machine includes a wireless connectivity device that is coupled to the currency acceptor within the security barrier. The wireless connectivity device provides for password-protected wireless access to the currency acceptor from outside the security barrier. Also disclosed is a method of limiting access to items stored within a vending machine that includes programming the currency acceptor to provide currency acceptor data to the wireless connectivity device.
