Recently, I have architected to develop a desktop applications, based on windows, Barcode, RFID, QT Platform, C++, SQL, SQLite, Wavetrend SDK, Sirit SDK, & ThingMagic Tag SDK, Active Tag, Passive Tag (30 bit numerical). Both technologies  targeting  large manufacturer and warehouse(own and client) where a large quantity of products processed & packed in  small, medium and big packages, finally placed into a pallet.  Each product packed in the package comes across various production processes(5 stages of assembly/process) finally approaching the Quality and Packing section. in Normal course, many orders processed at one cycle, there is a possibility that the products are mixed, missing or products held at one stage of processing due to incomplete status of the product at the particulat stage/level. But the dispatch section finds it very difficult to trace the missing products or missing packages to prepare for the complete delivery. This is a peculiar situation, where most of large manufacturers have  a problem that leads to bad delivery and delay in dispatch of containers, additionally it lags continuity of orders and deliveries.

To solve the production department process issues, we did evaluate and architect a intelligent Package and Stock Tracking system by using the barcode & RFID technology. Printing of Barcode labels for product information was already in practice, printing  serial numbers (16 digits number)  includes package number, batch number and product serial number.

This cost effective Barcode Tracking application was successfully deployed, after which the efficiency and accuracy is 100% now. But the question comes…….why do we need to go RFID? when Barcode itself gives 100% efficiency and it solves production process issues. Well the answer is simple, The difference is MANPOWER.  For barcode it is essential to involve manpower to scan the products, because the products are small in size, in case of packages which are normally big  can be scanned by fixing barcode readers permanently  on the conveyer, whereas the RFID antennas can achieve the same efficiency for products and packages, without the involvement of Manpower.

Additionally the advantage of RFID is that, the RFID readers can scan the products count, serial numbers which are inside the Package, counts those  boxes either at the dispatch area or the delivery point at client warehouse. RFID application is deployed in Incoming and Delivery where package of raw materials and finished goods are Actively tracked using Passive RFID tags. At end of the day tally of Stock become very efficient  with effective Stock IN and Stock Out of RFID tracking in place.
