Why Use PortalResizer's Magic Scan Filter?
When candidates capture signatures with smartphone cameras, poor indoor lighting often produces grayish backgrounds or tabletop shadows. The UPSC verification system can reject low-contrast signatures. Our built-in Magic Scan Filter automatically eliminates paper grain and boosts ink contrast, creating sharp, scanner-like clarity.
