Building on its North American presence through the recent opening of offices in the Willis Tower (formerly Sears Tower) in Chicago, AlpVision presented at Interphex 2011 its full range of digital on-packaging and on-dosage product authentication solutions. In the main lobby a hostess showing a sign reading Stop counterfeiters, smugglers and market diversion guided visitors to the AlpVision booth for live demonstrations. Over 70 US and international companies had the opportunity to meet and discuss with our regional manager to learn how their pharma products could benefit from the unique, simple and pragmatic AlpVision digital covert security solutions.
