QRCoder

Thanks to the ceaseless advancements in the field of technology, the ways in which information is processed and shared get easier to achieve and more convenient for both users and programmers. One interesting method of doing so concerns the use of Quick Response codes, which, similarly to barcodes, are fast-paced data transmission shortcuts that can be decoded using cameras.

As soon as smartphones became ubiquitous, this type of technology began spreading in a variety of mediums to maximize the efficiency of information transfer, with developers being able to implement the necessary components in their apps through libraries such as QRCoder.

When downloaded, the library provides programmers with a number of Demo utilities designed to showcase its flexibility, such as an example built on Microsoft’s Universal Windows Platform for those who want to incorporate Microsoft’s Fluent Design language into their apps and smoothen the layout in a way that matches the rest of the operating system’s native programs’ looks.

With the library’s features embedded, game developers can effortlessly add QR codes in video games to use as links to mobile companion apps that track players’ stats for perfecting their skills, or as hidden messages in different levels in the form of “Easter eggs”. Companies can create QR-based access cards for employees, similarly to the complex entrance permits issued by governments for citizens vaccinated against COVID-19, as an authorization method in both private and public institutions.

While coffee shops and restaurants can put up posters or leave coasters on tables with a code for the Wi-Fi credentials, physically-printed brochures can include QR codes with links to the event’s website for those interested to buy tickets. The latter use-case can benefit from the library’s built-in ability to change the color of the code in order to make it match with posters’ artwork, while companies trying to build on their brand image can also add their logo in the center of the code for a touch of uniqueness.

Whether you are looking to design an application destined to help users create custom business cards featuring easily scan-able contact details, or you wish to develop a program with templates for event fliers equipped with seamlessly integrated links towards ticket-purchasing platforms, QRCoder may be the right library for the job, considering its open source nature and lightweight form factor that makes implementation a breeze.
