Abstract: A system for data transfer between a server, a remote vending machine and a user computing device includes a remote vending machine for selectively providing an item stored therein to a user, a user computing device, an accounting server, a transaction server, and a data transfer network, wherein the vending machine comprises a door, a radio-frequency identification (RFID) antenna, a communication module, a memory, and a controller. The controller is communicatively coupled by a data transfer bus with the memory, the communication module and the RFID antenna. The user computing device comprises an authorization module and is configured to transfer to and receive data from the accounting server. The accounting and transaction servers, the vending machine and the user computing device are communicatively interconnected with one another by the data transfer network.
