BrandWatch Technologies is a company based in Portland, Oregon that seek to detect counterfeit products in the supply chain. BrandWatch has created a taggant material, a physical marker, that can be printed over barcodes or added to the ink used to print the barcodes themselves. This material, while invisible to the naked eye, is detectable using technology that they have developed.

BrandWatch enlisted the help of a four man team of Cal Poly Mechanical Engineering students to combine this technology with that of a barcode scanner. The device, capable of scanning barcodes, detecting the presence of the taggant material, and relaying this information to the user is the end result of this project.

The device is easily modifiable to request a taggant read or barcode scan first. A user simply has to pull the trigger and is walked through the process of scanning and reading via LCD screen prompts on the back of the handheld device. The data collected (both barcode and the presence of the taggant) is stored in a csv file on a small USB drive on the back of the device. This can easily be removed to transfer the data to a computer at the end of a work day.
