Behold one of the coolest business cards ever. Ramiro Pareja Veredas created this business card constructed from an actual Printed Circuit Board complete with working electronics. His information has been etched on the board and the card also comes with breakaway corners that make it double as a USB flash drive.
It only holds 24KB of memory which should be enough for a resume or cover letter. Produced in small batches, the cards cost about 5 euros a piece. Pretty awesome way to land a job.
