1. A surgical device for applying clips, wherein said surgical device comprises:
an elongate shaft extending from a housing;
an end effector extending from said elongate shaft, wherein said end effector comprises:
a first jaw; and
a second jaw, wherein said first jaw and said second jaw are movable relative to each other between an open position and a closed position;
a cartridge, comprising:
a storage chamber; and
a plurality of clips removably positioned within said storage chamber, wherein said plurality of clips comprises a first clip;
a crimping drive configured to move said first jaw and said second jaw to said closed position during a crimping stroke, wherein one of said plurality of clips is crimped around tissue of a patient during the crimping stroke;
an RFID tag positioned on said first clip, wherein said RFID tag comprises stored data, wherein said stored data on said RFID tag relates to an identifying characteristic of said first clip;
an RFID scanner configured to send an interrogation signal to said RFID tag and receive a first signal from said RFID tag in response to said interrogation signal, wherein said first signal comprises said stored data on said RFID tag; and
a controller in communication with said RFID scanner, wherein said controller is configured to:
compare said stored data received by said RFID scanner to a set of compatibility data stored in a memory of said controller; and
vary an operational parameter of said surgical device based on said stored data received by said RFID scanner.
