Abstract
Implementations feature scannable form techniques and systems. Some aspects feature an apparatus that includes a pen-camera device, an electronic clipboard to store the pen-camera device, and a docking station for the clipboard. The clipboard includes a retention clip to hold a form on a substantially planar surface, and a pen-camera storage compartment to store the pen-camera device. The clipboard includes a power supply interface for charging the pen-camera device, a communication interface to transmit image and location data from the pen-camera device, and electrical interfaces for the clipboard docking station. The pen-camera device can mark response data on the form, optically scan response data and location data on the form, and associate time-stamped information for the marked responses on the form for error checking and fraud detection. The scannable form can include an area for encoded information that identifies a location and arrangement of a position-coding pattern on the form.
