Piece o' cake! yep! we had a manager that wanted a "project plan" for this thing! we subverted the effort. we put it together in 2 days. rs445, rf card reader with antenna, card database, and interface to add/ remove/ disable/ enable cards from/ in/ to/ the system. we submitted the "project plan" the next morning. two words: project complete. ;) funmny we forgot to enable the manager's card. but it was great for bring pizza back to the office. just walk on up to hte door, reads the card in your shirt pocket, push the door open with your butt. -- Jonathan M.
