Parking meter communications for remote payment with updated display

1. A parking meter device comprising: a display and a communication subsystem configured to provide two-way wireless communication, the communication subsystem, or at least a portion of the communication subsystem, comprising a first power mode and a second power mode, the parking meter device configured to perform at least the following:

a) receive data indicative of a first payment for a parking session;

b) present an amount of time remaining in the parking session at the display;

c) wirelessly receive, by the communication subsystem, data for additional time in the parking session, the communication subsystem, or the at least a portion of the communication subsystem, in the first power mode;

d) the communication subsystem, or the at least a portion of the communication subsystem, entering the second power mode, wherein in the second power mode the communication subsystem wirelessly obtains further data pertaining to the additional time; and

e) present an updated amount of time remaining in the parking session at the display, wherein the display is powered and operational in the first and second power modes.

2. The parking meter device of claim 1 , wherein the first payment is a remote payment.

3. The parking meter device of claim 1 , wherein the first payment is a non-remote payment.

4. The parking meter device of claim 1 , wherein the parking meter device is configured to determine the updated amount of time remaining in the parking session to reflect the additional time.

5. The parking meter device of claim 1 , wherein the parking meter device is configured to present the updated amount of time remaining in the parking session at the display prior to expiration of the parking session or upon expiration of the parking session.

6. The parking meter device of claim 1 , wherein the parking meter device is configured to transmit a message comprising the time remaining in the parking session or the updated amount of time remaining in the parking session to a remote management system or to a wireless device of a user.

7. The parking meter device of claim 1 , wherein, when the communication system, or the at least a portion of the communication subsystem, is in the first power mode, the communication subsystem is enabled to receive an incoming message.

8. The parking meter device of claim 7 , wherein the parking meter device is configured to:

a) receive the incoming message; and

b) instruct the communication subsystem, or the at least a portion of the communication subsystem, to enter the second power mode in response to receiving the incoming message.

9. The parking meter device of claim 1 , wherein the parking meter device is configured to return the communication subsystem, or the at least a portion of the communication subsystem, to the first power mode.

10. The parking meter device of claim 1 , wherein in the second power mode the communication subsystem, or the at least a portion of the communication subsystem, uses more power than in the first power mode.

11. The parking meter device of claim 1 , wherein the first power mode is a sleep mode or a power down mode.

12. The parking meter device of claim 1 , wherein the second power mode is a full power mode or a power up mode.

13. The parking meter device of claim 1 , wherein the parking meter device remains operational during the first and second power modes.

14. The parking meter device of claim 1 , wherein the communication subsystem comprises a modem and supports active, standby, and dormant power modes.

15. A method of operating a meter comprising: a display and a communication subsystem, the method comprising:

a) receiving data indicative of a payment for a parking session;

b) presenting an initial amount of time remaining in parking session at the display;

c) wirelessly receiving, by the communication subsystem, data indicative of a second payment for additional time in the parking session, the communication subsystem, or at least a portion of the communication subsystem, in a first power mode;

d) the communication subsystem, or the at least a portion of the communication subsystem, entering a second power mode, wherein in the second power mode the communication subsystem wirelessly obtains further data pertaining to the second payment; and

e) presenting an updated amount of time remaining in the parking session at the display, wherein the display is powered and operational in the first and second power modes.

16. The method of claim 15 , comprising determining the updated amount of time remaining in the parking session to reflect the additional time.

17. The method of claim 15 , wherein presenting the updated amount of time remaining in the parking session at the display is performed prior to expiration of the parking session or upon expiration of the parking session.

18. The method of claim 15 , comprising transmitting a message comprising the time remaining in the parking session or the updated amount of time remaining in the parking session to a remote management system or to a wireless device of a user.

19. The method of claim 15 , comprising instructing the communication subsystem, or the at least a portion of the communication subsystem, to return to the first power mode.

20. The method of claim 15 , comprising instructing the communication subsystem, or the at least a portion of the communication subsystem, to enter the second power mode.

21. The method of claim 15 , wherein the first power mode is a lower power mode than the second power mode.

22. The method of claim 15 , wherein the first power mode is a sleep mode or a power down mode.

23. The method of claim 15 , wherein the second power mode is a full power mode or a power up mode.

24. The method of claim 23 , wherein the meter remains operational in both the first and second power modes.
