1. A medical waste collection system comprising:
a medical waste collection device for providing suction at a surgical site;
a manifold releasably couplable to the medical waste collection device and defining a pathway through which the medical waste collection device is configured to provide the suction to the surgical site, the manifold including an RFID tag including a first memory bank storing an identifier for the RFID tag, a second memory bank for storing electronic identification data for the manifold, and a third memory bank for storing user data, the third memory bank including a plurality of memory blocks with one or more first memory blocks of the plurality of memory blocks being locked in a permanent read-only state and one or more second memory blocks of the plurality of memory blocks not being locked in the permanent read-only state according to a predefined lock pattern for verifying the RFID tag by the medical waste collection system; and
a controller of the medical waste collection device that is configured to, responsive to the manifold being coupled to the medical waste collection device:
determine that the one or more first memory blocks each exhibits a behavioral characteristic consistent with the permanent read-only state and the one or more second memory blocks each does not exhibit the behavioral characteristic of the permanent read-only state; and
enable operation of the medical waste collection device to provide the suction at the surgical site responsive to determining that the one or more first memory blocks each exhibits the behavioral characteristic consistent with the permanent read-only state and the one or more second memory blocks each does not exhibit the behavioral characteristic of the permanent read-only state.
