ABSTRACT:
A subscription-based computing device has hardware and a subscription enforcer implemented in the hardware. The enforcer has an accumulator that accumulates a usage value as the computing device is being used and an expiration value register that stores an expiration value. The enforcer allows the computing device to operate in a subscription mode without hindrance and with full use when the usage value is less than the stored expiration value, and allows the computing device to operate in an expiration mode with hindrance and without full use when the usage value reaches the stored expiration value to signal that the subscription for the computing device has expired.
