cause the display unit to present an indication of the reservation corresponding to the command.

8. The vending machine of claim 6 , wherein to place the command in the vending queue, the instructions, when executed, cause the one or more processors to:

transmit, to the user device, an indication of a queue position corresponding to the command.

9. The vending machine of claim 1 , wherein the instructions, when executed, cause the one or more processors to:

determine that a second user device that does not correspond to a reservation record stored in the reservation database is proximate to the vending machine;

transmit, to the management server, a reservation identifier obtained from the second user device; and

receive, from the management server, an indication of a second reservation record corresponding to the second user device.

10. The vending machine of claim 9 , wherein the instructions, when executed, cause the one or more processors to:

determine that the vending machine is capable of vending items included in a second list of items; and

transmit, to the second user device, a notification enabling the user of the second user device to vend items included in the second list of items at the vending machine.

11. The vending machine of claim 10 , wherein the instructions, when executed, cause the one or more processors to:

responsive to receiving, from the second user device, a request to vend the items included in the second list of items, transmit, to the management server, a request to vend items included in the second list of reserved items, wherein transmitting the request causes the management server to delete a copy of the second reservation record stored at a second vending machine.

12. The vending machine of claim 9 , wherein the instructions, when executed, cause the one or more processors to:

determine that the vending machine is not capable of vending items included in the second list of items;

transmit, to the management server, a request to provide, to the second user device, a list of vending machines that are (i) proximate to the vending machine (ii) capable of vending the items included in the second list of items.

13. The vending machine of claim 1 , wherein:

the vending machine is located at a location having two or more vending machines located thereat; and

the instructions, when executed, cause the one or more processors to:

responsive to determining that the user device is proximate to the vending machine, transmit, to the user device, an indication of a position of the vending machine relative to another vending machine of the two or more vending machines.

14. A vending machine comprising:

one or more processors;

one or more transceivers adapted to communicate with a management server over a one or more communication networks;

a display unit;

a reservation database configured to store reservation records of reservations for items available at the vending machine, wherein each reservation record includes a list of reserved items; and

one or more non-transitory memories coupled to the one or more processors, the reservation database, the display unit, and the one or more transceivers, the one or more non-transitory memories storing a set of computer executable instructions that, when executed by the one or more processors, cause the vending machine to:

configure the display unit to display an indication of the vending machine interpretable by at least one of a user device and a user of the user device;

receive, from a management server, a request to vend a list of items included in a reservation record corresponding to the user device, wherein the request is received responsive to the user device transmitting, to the management server, a message based on the displayed indication of the vending machine;

issue a command to vend the list of reserved items for the reservation record.

15. The vending machine of claim 14 , wherein to configure the display unit to display the indication of the vending machine, the instructions, when executed, cause the vending machine to:

periodically change the displayed text string that uniquely corresponds to the vending machine.

17. The vending machine of claim 14 , wherein to configure the display unit to display the indication of the vending machine, the instructions, when executed, cause the vending machine to:

display a barcode that encodes an identifier of the vending machine.

18. A computer implemented method implemented at a vending machine that includes (i) one or more processor, (ii) one or more transceivers adapted to communicate with a management server over a one or more communication networks, (iii) a display unit; and (iv) a reservation database configured to store reservation records of reservations for items available at the vending machine, wherein each reservation record includes a list of reserved items; the method comprising:

determining, via the one or more processors, that a user device corresponding to a reservation record stored in the reservation database is proximate to the vending machine, wherein the determination occurs without the user touching the display unit;

obtaining, via the one or more processors, a reservation identifier corresponding to the reservation record stored in the reservation database;

transmitting, to the management server, a request to vend items included in the list of reserved items for the reservation record corresponding to the reservation identifier;
