Without a doubt, there is a marked difference between physical and digital technologies. However, as the world becomes more connected through the use of technology, these differences are starting to become blurred in the benefit of interconnectivity. One of the best examples of this paradigm change is Smart Paper. Creating significant links between the physical and the digital worlds, this technology aims at enhancing communication and interactivity. In order to inform you, this guide will go over the most important aspects of this revolutionary technology.

What is Smart Paper?

Despite looking just like normal paper, smart paper can retain a great deal of digital information that can later be used in many different real-world applications. 

By using radio-frequency identification (RFID) tags, smart paper hosts sensor-friendly features that can be read and interpreted by certain specialized pieces of technology. These capabilities infuse the paper with the capability of connecting to related virtual assets such as web pages and other digital platforms, greatly expanding its real-world functionalities and applications. 

As a result, people can use smart paper as a physical medium that directly links its users to digital information, expanding its reach and creating important connections between the physical and the digital worlds. This ability can be incredibly helpful to expand real-world interactions into the digital world. At its best, this technology allows users to seamlessly move between the physical and the digital without skipping a beat. In addition to its reality-enhancing capabilities, smart paper has the ability to eradicate document counterfeiting by making it extremely difficult.

How Does Smart Paper Work?

As previously mentioned, smart paper works by using a radio-frequency identification tag that is printed directly on its body. Originally, these tags had to be applied in the form of a sticker or drawn directly onto the piece of paper. Recently, however, technology has evolved to allow inkjet printers to apply silver nano-particles to a piece of paper, transforming it into smart paper. Using conductive inks, this tag can be detected and read by compatible technologies. Once it has been applied, conductive ink functions as an RFID antenna, allowing RFID readers to detect its unique ID, allowing various types of interaction. Basically, when the signal that is emitted by the RFID tag is interrupted by your hand, the reader registers the interaction. The reader then uses algorithms to recognize specific movements.

How Can Smart Paper be Used?

Apart from emitting signals that can be picked up and read by compatible technologies, smart paper offers a series of interactive possibilities to its users. Mainly, these interactive possibilities exist in the realm of hand gestures such as waving or swiping in a particular direction.

Smart Paper has many different real-world applications. Its ability to transmit information to a corresponding piece of digital software functioning through a device (like a smartphone) can be used in many industries, businesses and academic scenarios. Its in-store uses are incredibly versatile, ranging from getting information on your smartphone directly from a product's label to using printed coupons in a digital setting.

Additionally, smart paper has many interesting social applications. By applying an RFID tag on your business card, you could have your personal information delivered directly to the smartphones or tablets of the people you interact with. It goes without saying that this ability can be extremely helpful for networking purposes. 

As if this wasn't enough, smart paper can be potentially used to reduce crimes such as theft and money or document counterfeiting. As a matter of fact, RFID tags can function as small, unobtrusive anti-theft devices. 

What are the Most Important Aspects of Smart Paper?

• Internet connectivity: Each piece of smart paper content is hosted online and has its own URL address. It can also have its own domain or subdomain. This gives internet users the additional possibility of reaching the content through its unique URL. 

• Interactivity: The online, digital content of smart paper has the ability to be interacted with by users. Using interactive menus and tables of content, users can skip sections, find particular pieces of information or explore. It's even possible to create content that has game-like aspects such as quizzes or decision-making processes. 

• Optimization for Mobile Device Use: One of the main advantages of smart paper is its ability to connect directly to mobile devices. Using universal technologies that are compatible with a wide range of devices such as HTML5, smart paper can provide users with a practical and way of direct interaction.

• Shareability: Another important advantage that smart paper can offer is shareability. Through its direct connection with digital devices, you can easily and quickly share smart paper through social media sites like Facebook, Twitter or Linkedin.

• Search optimization: Smart paper can also be optimized for searches, ensuring people will be able to find a specific piece of information quicker and more easily. 

• Water detection: Smart paper also has industrial applications. Without a doubt, one of the most innovative of these applications is water detection. This can be incredibly useful considering that, in large-scale manufacturing plants, a water leak can be a complete disaster. Smart paper prevents this by detecting the leak and immediately deploying an alarm signal. This can prevent great losses by prompting a quick and opportune reaction from the people in charge. 

Is Smart Paper the Way to Go?

After going through its characteristics one by one, it's easy to see why smart paper has been gaining so much attention over the last couple of years. It is evident that consumers are starting to realize the wide range of possibilities for using smart paper. The future of smart paper offers great potential in terms of industrial and academic applications.
