Systems and methods relating to document and fastener identification

A system for document processing, comprising:

• a document transfer end effector, wherein the document transfer end effector comprises (i) a body, (ii) a suction applicator disposed adjacent to a bottom portion of the body, and (iii) a document pincher comprising an arm and a document gripper, the arm coupling the document gripper to the body;
• and
• a controller unit comprising a processor, wherein the controller unit is in operable communication with the document transfer end effector, wherein the controller unit is configured to transfer a document or document stack from a first location to a second location by:
• contacting the suction applicator with a first surface of the document or document stack to subject the first surface to a suction force;
• lifting the document or document stack in contact with the suction applicator;
• contacting the document gripper to a second surface of the document or document stack to position the document or document stack between the document gripper and the bottom portion of the body, wherein the second surface is opposite the first surface;
• and
• moving the document transfer end effector to transfer the document or document stack from the first location to the second location.
