ABSTRACT:
Embodiments of the invention involve modifying non-volatile data fields in the integral memory components of consumable cartridges (and, in some embodiments, data fields in the utilizing device memory) such that the consumable cartridges become compatible with only a small subset of utilizing devices, thereby substantially reducing their potential value to a thief or unauthorized borrower.
