14. A payment number intermediation method performed by an intermediary positioned along a communication path between a client and a server, comprising:
receiving a payment message from the client;
after receiving the payment message, detecting a credit card account number in the payment message;
after detecting the credit card account number, replacing the credit card number with a one-time use credit card number to create a modified message; and
sending the modified message along the communication path to the server.
15. The method of claim 14, wherein the replacing of the credit card account number includes requesting the one-time use credit card number from a credit card account service provider.

setting the snooze interval to a constant bit rate value when a number of transmitted data packets exceeds a first threshold value
6. The method of claim 5, further comprising:
when communications are bi-directional communications, placing the device in the reduced power state until transmission of a data packet;
when the communications are uni-directional communications, setting a maximum snooze interval value;
processing further data communications; and
adjusting the snooze interval based on a number of packets received in the further data communications.
7. The method of claim 6, further comprising:
reducing the snooze interval when the number of packets received in the further data communications is greater than a second threshold value; and
