The university of South Dakota have developed a new Type of QR-code invisible, ready to application on any material. The system is based on nanoparticles tecnology and is used to discovered fake material. The technology could come soon in the industrial process.
The Quick Response code a monochrome square, when is scanned with smartphone, directs to specific content sites, they do not have become a mass phenomenon. The recent smartphones, with “Near Field” recognition devices have inflicted another blow to QRcode. Yet they survive, and they might have found their raison d’etre in a U.S. study.
The university of South Dakota have developed a new Type of QR-code invisible, ready for, once in production, to an infinite number of products. Paper, textiles, plastics, glass, stone, all receptors are ideal for the new generation of QR. But in addition to the known uses, these new codes can function as a digital watermark, carrying out an authentication function, as well as data recovery. The human eye can not detect them, and become visible to infrared light. It could represent a system of identification to distinguish fake money from real banknotes, documents and counterfeit clothes: simply point your smartphone – if it has an infrared vision – and this instantly recognize what the user is facing.
The University of South Dakota also specifies that these new codes are, unlike the QR-Code classics rather difficult to duplicate, because of the complexity of processing. They are created using nanoparticles combined with blue and green fluorescent inks, and printed on the surface to be treated with a printer of aerosols. A process that takes about an hour and a half but that industrial regime, the researchers say, may not take more than 15 minutes.
You can easy modify the code by inserting more information or data not readable by common tools, in order to provide an element of use, even for legal uses. It may not be the end of counterfeiting, but the revenge of the QR-Code seems to be significant.
The barcode on a gravestone: Funeral director’s interactive headstones launch tributes to the departed with the swipe of a mobile phone.
As an enduring tribute to a life lived, gravestones have changed little over the centuries. Until now.
Funeral directors are giving headstones a rather modern makeover – by making them interactive.
Barcodes are being placed on the gravestones to allow visitors to find out more about the person laid to rest there. When scanned on a smartphone, the square codes – known as Quick Response or QR codes – launch a website which contains a biography of the deceased.
The page can include a profile of the person, photographs and videos of them and tributes from family and friends.
Loved ones can use a password to create and update the website and add more comments or memories as time goes by.
The idea enables visitors to graveyards to learn more about those buried there than just their name, age and date of birth.
If they know the password, they can even add their own tributes.
As well as graves, the QR codes can be added to memorials and tribute plaques on benches.
The first funeral director to provide the service in the UK is Chester Pearce, in Poole, Dorset.
Managing director Stephen Nimmo said the QR codes are etched onto a small granite or metal square before being embedded or glued on to a gravestone.
He added: ‘I thought we could use technology to provide more information about people who have died to bring back the memories.
‘People can make their websites as simple or as complicated as they like and add as much or as little information as they want.
‘They will be able to use a photo gallery, upload video, and constantly update a page.
‘For example, if someone has died but their daughter becomes a mum, you could add that.
‘I am a very traditional funeral director but using this technology is a positive way to help remember people. People often wander around cemeteries and look at gravestones and wonder who that person was. By using the QR codes they can find out.’
But the technology doesn’t come cheap, with the QR codes costing up to £300 and an additional charge of £95 for the hosting and set-up of the website.
One of the first to use the technology is Gill Tuttiett, who has had a QR code installed on the grave of late husband Timothy at a church, near Poole.
Mrs Tuttiett, 53, decided to install the code because her husband, who died last year of heart failure at the age of 55, was always interested in new technology.
Visitors who scan the code on his gravestone see information about the former airport operation manager’s family, schooling and career. Mrs Tuttiett said: ‘I think this is the way forward and Tim would have wanted that.’
