Abstract
A module installable in a machine includes a memory device attached thereto for storing electronic data associated with the module. The memory device allows an individual to verify the authenticity or inauthenticity of the module without having to install the module into the machine. The memory device includes a sensory signal output device (e.g., a visual, audible, or tactile output device) that provides a sensory signal indicating authenticity or inauthenticity of the module. To verify authenticity or inauthenticity of the module, the individual initiates a query signal, for example by activating a switch on the module or by using a handheld antenna to impart an electromagnetic field onto the CRUM, and checks for the sensory signal output by the CRUM. The sensory signal may be capable of communicating a visual or audible trademark associated with the module. Data stored in the CRUM may include anti-arbitrage variables associated with the module.
