Laser Etched QR Codes
Our devices are talking to each other every day, and with all this chatter going on, making new connections or transferring data should be an effortless process. Technologies such as NFC (Near Field Communication) and QR (Quick Response) Codes help to make these digital interactions smooth and simple. Continue reading to discover how you can use laser cutting to integrate these technologies into your products.
How does NFC and QR work?
For NFC to work, information is encoded onto an embedded chip. When two devices containing NFC chips come into contact (usually in the form of a bump or light tap) a process is engaged – payment could be transferred, data and audio connections established or other tasks involving interaction between the two devices.
QR codes operate much like a barcode; they contain a set of reference information that can be scanned using the camera on a smartphone. This prompts the device to access information such as a website address, play a video, or (as in the example above) display login credentials.
Why is this useful for your brand?
The ability to seamlessly connect can give your customers immediate access to a deeper level of information. This means you can add collateral such as image galleries, video clips and other detailed supporting content without consuming valuable real estate on your product. There is much scope to have fun with QR Codes as well as to use them for sensible, straightforward communication.
In the example shown here, Instructables user BWRussell needed a way to share the login details for his wireless network. Tired of spelling out the passphrase to relatives and visitors, he constructed his own dongle that houses an NFC chip and a laser etched QR Code. All visitors need to do is tap or scan the code with their mobile device, and they will be granted access to the network.
It is worth noting that when it comes to the actual physical QR code, a similar functional outcome can be achieved with a desktop printer… however, a laser etched QR code has a greater sense of quality and purpose.
