Abstract:
1. A method for permitting a cashless vend from a cashless vending system, comprising: allowing a user's Radio Frequency Identification card to be scanned by a display/reader of a vending machine, wherein a reader portion of the display/reader is capable of scanning the user's Radio Frequency Identification card and wherein a display portion of the display/reader is capable of displaying information to the user, wherein the vending machine comprises a Vending Machine Controller that supports an international Multi-Drop Bus/Internal Communication Protocol standard, wherein the vending machine includes a NetVend interface that communicates, via a Multi-Drop Bus/Internal Communication Protocol interface, with the Vending Machine Controller, wherein the NetVend interface contains an embedded machine ID number that uniquely identifies the vending machine, and wherein the NetVend interface contains a nonvolatile memory for storage of vending data; allowing the user's RFID number to be determined by the NetVend interface associated with the vending machine; allowing the NetVend interface associated with the vending machine to contact a central server by transmitting the user's RFID number to the central server, wherein the central server contains a database for storing user Identifiers and an associated allowable credit or available cash data for the user Identifier, wherein the central server is capable of authenticating users for granting/denying access to a vending machine, receiving transaction data, and monitoring and controlling a plurality of vending machines; receiving, in the central server, the transmitted user's RFID number; accessing, in response to the receipt of the transmitted user's RFID number, the database for storing user Identifiers; determining, based on information in the database, an allowable credit or available cash amount associated with the received user's RFID number; transmitting, if the allowable credit or available cash amount is above a predetermined amount, an allowable credit or available cash amount associated with the received user's RFID number and a transaction ID number to the NetVend interface associated with the vending machine; receiving, in the NetVend interface associated with the vending machine, the transmitted allowable credit or available cash amount and the transaction ID number; allowing the allowable credit or available cash amount to be displayed for the user by the vending machine; allowing the user to make a selection from items available in the vending machine; allowing the NetVend interface to determine transaction/vend data associated with the user's vending machine selection; allowing the NetVend interface to transmit the determined transaction/vend data associated with the user's vending machine selection and the transaction ID number to the central server; receiving, in the central server, the determined transaction/vend data and the transaction ID number; transmitting, from the central server, in response to receipt of the determined transaction/vend data and the transaction ID number, an acknowledgement to the vending machine; receiving, in the vending machine, the acknowledgement from the central server; and allowing, in response to receipt of the acknowledgement from the central server, the vending machine to permit the cashless vend.
