  • Subscription based monitoring system and method
    Patent number: 6413213
    Abstract: A system (10) for subscription monitoring of a medically significant characteristic of a bodily fluid which includes a meter (12), a ROM circuit (36), a test strip (34), and a registry (50). Meter (12) has an identifier corresponding to a subscription user. ROM circuit (36) is provided with test strips (34), and contains calibration data and an identifier. The meter (12) requires an activation code before it may conduct a biosensing test. The meter (12) communicates with registry (50) through communication means (40) and provides the meter identifier and ROM circuit identifier. Registry (50) checks for valid association of the meter identifier, ROM circuit identifier, and user identifier. If a valid association is established, the registry (50) provides an activation code to the meter (12), enabling meter (12) to conduct testing during a subscription period.
