Abstract

Digital image capturing and processing system comprising a digital image capturing and processing module, and an integrated electronic weigh scale module having a load cell that is centrally located with respect to the digital image capturing and processing module. The digital image capturing and processing module electrically interfaces with the electronic weigh scale module by way of touch-fit electrical inter-connectors that automatically establish all electrical interconnections between the two modules when the digital image capturing and processing module is placed onto the electronic weigh scale module, and the electronic load cell bears the weight of the digital image capturing and processing module.
