Patent Images
1. A subscription system, comprising:
- one or more processors; and
one or more memory resources storing instructions that, when executed by the one or more processors, cause the subscription system to;
receive an identification number (ID) and a sequence number, the ID number corresponding to a subscription device and the sequence number corresponding to a credit last received by the subscription device, wherein the credit indicates a subscription limit of a utilized resource met by the subscription device;
search a database to locate a pin associated with the ID number and the sequence number; and
in response to locating the pin, transmit an additional credit to the subscription device to enable the subscription device to utilize the resource up to an extension amount above the subscription limit;
wherein the resource corresponds to one of a number of pages printed, an amount of ink consumed, a usage time, or a number of access events on the subscription device, and wherein the subscription limit and the extension amount are encrypted via an asymmetric key algorithm in the last received credit and the additional credit respectively.
