SignatureGem® 4x5 is a durable large-sized electronic signature pad with digitizing pen. The signing area is large enough to accommodate paper forms or receipts for clients while you maintain a paperless electronic copy. The pen features interchangeable inking and stylus tips, and the pad is powered only by the computer's data port.


With the rugged signing surface, these models show the signature on the computer screen.
