The software can recognize most 1D linear bar code to check readability, consistency and human readable match. Sequential and matching verification will automatically check for missing or duplicate serial numbers. The software can recognize and decode 2D Data Matrix bar codes to check readability and basic print quality. Sequential and matching verification will automatically check for missing or duplicate serial numbers. Bar coding has transformed value chain management over the last twenty years, and the ability to capture data automatically at every significant point in the value chain enables faster and more efficient management. We are moving closer to the point when all the trading organizations in any value chain can begin to work together as one linked enterprise, with the scanning of products providing a flow of information that informs all other actions. Bar coding system consist of infrastructure, either wired or wireless that connects number of mobile computers, handheld scanners, and printers to one or many databases that store and analyze the data collected by the system. This system is mainly used for quality assurance in Pharmaceutical Industry, Food & Beverage Industry, Cosmetic Products Industry, Printing Press Industry, Packaging Industry etc. The different applications of system include: • To verify Label Pattern and Color Verification. • To check and verify OCR (Optical Character Recognition), Barcode, Pharmacode, 2D code on Label. These OCR contains the detail of the product like Batch no., M.R.P., Manufacturing Date, expiry date etc. • To check & verify the Numbers (Digits/Characters) at the time of Printing on Scratch-Cards, Recharge Vouchers, ATM/Debit/Credit Cards, Lottery Coupon, Application Forms etc. • Most useful to “Track N Trace” system which has been recently made compulsory in many countries for Pharmaceutical Products. • To verify the Printing Quality.
