Once lit up with the laser, the code can be scanned with a mobile phone, but the technique allows deeper levels of security with the ability to conceal information that can only be read with a microscope. "We can also change our parameters to make it even more difficult to counterfeit, such as controlling the intensity of the upconverting light or using inks with a higher percentage of nanoparticles," said Jeevan Meruga, who led the research. The process is known as 'upconversion' where the nanoparticles absorb photons at a certain wavelength and then emit them at a shorter wavelength visible in normal light. The invisible QR code, made by scientists at the University of South Dakota and South Dakota School of Mines and Technology, is made of tiny nanoparticles mixed into fluorescent ink, which can only be seen when illuminated with a near-infrared laser. Researchers have found out how to print them with inks that are only visible under laser light, giving them potential in the fight against fake banknotes and counterfeiting, which the OECD estimates costs the world economy more than $250 billion a year. Smartphones can scan them in printed adverts to navigate to company websites. You can also deploy barcode generating webservice on your own webserver.ĩ9.99% uptime guarantee: performance test shows de facto response time of 30 ms or less for multiple clients requesting barcodes during regular business hours.īar Code Generating Webservice supports most linear and 2D barcode symbologies: Code39, Code128, UPC-A, UPC-E, EAN13, EAN8, Bookland, ISBN, POSTNET, Code93, Code25, Interleaved 25, Codabar, MSI / Plessey, Data Matrix, PDF417, QR Code and Aztec Code.īar code image could be in one of the following formats: BMP, GIF, JPeg, TIFF and PNG.Scientists in the United States have made an invisible version of square modern barcodes using nanoparticles and fluorescent ink to help in the fight against counterfeiting.īlocks of black and white Quick Response (QR) codes are increasingly common in marketing and can hold a hundred times more information than traditional barcodes. You can integrate published webmethods with your own client desktop application to generate barcode. It uses XML (eXtensible Markup Language) that follow Simple Object Access Protocol (SOAP) to stream bar code images from our web server to your computer. Webservice is a software system designed to support interoperable machine-to-machine interaction over a network.īar Code Generating Webservice is provided by BarCodeSoft.
