Abstract

One variation of a method for controlling access to products from a vending machine includes: locking a door of the vending machine; recording an initial inventory of products arranged within the vending machine based on signals received by a radio antenna arranged within the vending machine and read by a radio frequency identification reader; initiating a transaction in response to receiving a cashless payment mechanism from a patron; unlocking the door in response to authentication of the cashless payment mechanism; in response to closure of the door, recording a final inventory of products within the vending machine based on signals received by the radio antenna and read by the radio frequency identification reader; and initiating a payment with the cashless payment mechanism for a difference between the initial inventory and the final inventory to complete the transaction.

further comprising a second radio antenna arranged over a second shelf in the column of shelves and configured to output an excitation signal to excite radio frequency identification tags arranged on products placed on the second shelf; and

wherein the processor is configured to record the initial inventory of products within the kiosk based on signals received from the radio antenna and the second radio antenna by the radio frequency identification reader.

6. The vending system of claim 3, wherein the door lock, the door sensor, the radio antenna, and the housing comprise a vending kit configured for retrofitting onto an existing kiosk.

7. The vending system of claim 6:

wherein the housing comprises a replacement door for the kiosk;

wherein the door sensor is integrated into the replacement door; and

wherein the radio antenna comprises a dipole antenna arranged along the frame of the replacement door.

8. The vending system of claim 2:

further comprising a first radio frequency identification tag arranged on a first shelf, in the column of shelves, over a first region of the first shelf designated for a first product type comprising a metallic packaging; and

wherein the processor is further configured;

to determine that a unit of the first product type is in inventory in the kiosk and arranged over the first region of the first shelf in response to a scan of the first shelf by the radio frequency identification reader that excludes a signal associated with the first radio frequency identification; and

to determine that a unit of the first product type has been removed from the first region of the first shelf in response to a scan of the first shelf by the radio frequency identification reader that comprises a signal associated with the first radio frequency identification tag.

9. The vending system of claim 1:

wherein the payment collection module comprises a wireless communication module configured;

to detect a mobile computing device proximal the kiosk;

to download payment information from the mobile computing device;

wherein the processor is further configured to generate a digital receipt based on the difference between the initial inventory and the final inventory in response to conclusion of the new transaction; and

wherein the payment collection module is further configured to wirelessly transmit the digital receipt to the mobile computing device.

10. The vending system of claim 9:

wherein the processor is further configured to access product information and real-time pricing data of products stocked in the kiosk based on identification signals received from radio frequency identification tags via the radio antenna prior to the new transaction; and

wherein the wireless communication module is further configured to transmit product information and real-time pricing data of products stocked in the kiosk to the mobile computing device for visual review at the mobile computing device in response to initialization initiation of the new transaction.

11. The vending system of claim 1:
