QR codes seen only under infrared light combat forgeries

Invisible QR CodesA team in South Dakota have created invisible printing for security barcodes.

Stanley May, a professor at the University of South Dakota, and a team that includes Jon Kellar, from that institution’s School of Mines and Technology, have combined the use of an invisible ink and a special printing process in order to make invisible QR codes that can be used to identify counterfeit goods.

The barcodes can be seen only when they are viewed under an infrared light.

The research team from the college found a way to add QR codes that cannot be seen by the unassisted eye, to various types of surfaces including paper. This suggests that they could be added to items that are commonly forged, such as official documents, paper currency, and even designer products.

These QR codes could make it much more challenging for counterfeits to be convincingly made.

May and his team have been working over the last few years to create a clear ink solvent, and have now applied nano-particle technology to this accomplishment in order to create the ink that can be seen only when displayed under infrared. The most recent effort involved using this ink in a way that would make it printable. This included the involvement of William Cross, in addition to Kellar.

Through the use of a special aerosol lab printer, the research team was able to apply invisible, basic shapes and letters to various surfaces. The idea to print QR codes came from Jeevan Meruga, a graduate student who had been working with Kellar. He thought up the concept and successfully tested it with the printer before presenting it to Kellar, who said that he wasn’t sure what it was at first. However, he explained that “I quickly figured out what it was and how important this could be.”

The team is now working to perfect the printing of the invisible QR codes so that they can be used in anti-counterfeiting operations. It has been suggested that it could be applied to items such as currency, or identification such as passports or drivers licenses. This would make forgeries much harder to accomplish.

QR codes with medical histories help patients in emergencies

QR Codes MedicalBy personalizing the barcodes, first responders can gain immediate access to patient information.

A contest called the Startup Weekend Health competition in Philadelphia was held for the second time this year, and in this instance, it was won by a concept for using personalized QR codes that provide emergency responders, such as paramedics, to scan them in order to obtain relevant patient data.

This use of the barcodes allows the medical professionals to obtain vital information right away.

Even if a patient has been rendered unconscious, is in shock, or is unable to provide accurate information, the QR codes give the first responders access to his or her medical information. The hope is that by using technology in this way, it could help medical personnel to reduce the chance of accidentally administering the wrong type of treatment to a patient.

The data revealed by the QR codes could help an emergency responder to better save a life.

This is because by scanning the QR codes in an emergency room or even out when a paramedic is responding to a call, the patient’s allergies, the medications that he or she is taking, and his or her medical conditions can be revealed. This can help the responder to make a decision that is more appropriate to the needs of that specific individual.

Moreover, When the right app is used, it becomes possible for QR codes to give the medical responders the ability to send out a text message to the patient’s emergency contacts. This way, even more information can become available, and personal support can become available to that patient.

The entire concept for the QR codes used in this way was pitched for the contest by a team from the In Case of Emergency (mICE) program. The leader of that group, David Bendell, made the actual pitch, and the entire plan for the program itself was put together by a team of seven people within 48 hours of the pitch itself. Though they won first prize – an interview with DreamIt Health, their main concern is now that two members of the team (including Bendell, himself) are international students. They will need to find full time jobs before May 2013 or their visas will run out before they can continue this project.
