Method and system for paperless electronic queue ticketing

1. A computer-implemented method for paperless electronic queue ticketing, the

method comprising:

reading, by a processor of a user device, an electronic ticket code displayed on a ticket device, the electronic ticket code having information and instructions for an electronic ticket;

decoding, by the processor of the user device, the information and instructions in the electronic ticket code; and

sending, by the processor of the user device, a signal to a sensor on the ticket device to obtain the electronic ticket, wherein the signal is provided to the sensor on the ticket device by a speaker in the user device.

2. The computer-implemented method of claim 1 , wherein the electronic ticket code is a matrix barcode.

3. The computer-implemented method of claim 1 , wherein the sensor on the ticket device is a light sensor.

4. The computer-implemented method of claim 1 , wherein the sensor on the ticket device is a speaker.

5. The computer-implemented method of claim 1 , wherein the signal is a radio-frequency identification signal and the sensor on the ticket device is a radio-frequency identification sensor.

6. The computer-implemented method of claim 1 , wherein the signal is a near field communication signal and the sensor on the ticket device is a near field communication sensor.

7. The computer-implemented method of claim 1 , wherein the ticket device is not connected to a computer network.

8. The computer-implemented method of claim 1 , wherein the user device is not in wireless communication with the ticket device.

9. The computer-implemented method of claim 1 , wherein the electronic ticket is obtained without physical contact between a user device and the ticket device.

10. The computer-implemented method of claim 1 , wherein the electronic ticket is obtained without physical contact between the user and the ticket device.

11. The computer-implemented method of claim 1 , wherein the information and instructions in the electronic ticket code comprise an electronic ticket number and instructions for sending a signal to the ticket device.

12. The computer-implemented method of claim 1 , wherein the information and instructions in the electronic ticket code comprise a predetermined duration of time in which the signal may be received by the sensor on the ticket device.

13. A system for paperless electronic queue ticketing, the system comprising:

a user device display;

a user device memory;

a user device processor communicatively coupled to the user device display and the user device memory, where the user device processor is configured to:

read, by the user device display, an electronic ticket code displayed on a ticket device;

decode information and instructions in the electronic ticket code; and

send a signal to a sensor on the ticket device to obtain an electronic ticket, wherein the signal is provided to the sensor on the ticket device by a speaker in the user device.

14. A computer program product for paperless electronic queue ticketing, the computer program product comprising:

a user device computer readable storage medium having a computer readable program code embodied therewith, the computer readable program code configured to:

read the electronic ticket code displayed on the ticket device;

decode information and instructions in the electronic ticket code; and

send a signal to a sensor on the ticket device to obtain the electronic ticket.

15. The computer program product of claim 14 , wherein the signal is provided to the sensor on the ticket device by a speaker in the user device.
