Abstract

A device for measuring length of an object, comprising a coilable tape having a plurality of machine-readable measurement codes on at least one surface, each of the plurality of machine-readable measurement codes encoding for a length value corresponding to a length, a scan engine having a reading zone through which the coilable tape can be extended, the scan engine being configured to detect a machine-readable measurement code positioned within a reading zone, a processor in communication with the scan engine, and an output means selected from one or more of a visual display, a wireless transmitter, a memory, and a remote device, wherein upon extending the coilable tape to a particular length, such that the machine-readable measurement code encoding for the corresponding length value is positioned within the reading zone, the scan engine detects the machine-readable measurement code, receives the corresponding length value and provides the corresponding length value to the processor, the processor processes the corresponding length value, and provides the processed length value to the output means.
