What are QR Codes?
Quick Response Codes (QR codes) are simply a type of two-dimensional barcode that can only be read using smartphones or other devices that are dedicated to QR reading. The devices that can read a QR code connect directly to texts, emails, websites, phone numbers and many more.
What can be encoded into a QR Code?
Basically, a QR Code is an image-based hypertext link that can be used offline. This implies that any URL can be easily encrypted into a QR Code and any webpage can be automatically opened as a result of scanning the barcode. Therefore, if you want to encourage somebody to like your Facebook page, you must have your Facebook profile page as the URL–. Moreover, if you want your video to go viral, you need to encode the URL in your QR Code. The choices are unlimited.
Besides website URLs, a QR Code can also have a phone number so that when it’s scanned it encourages the user to call that specific number. Equally, you can also encode an SMS text message, V-card data or even plain alphanumeric text. Once the content is embedded within the QR Code, the QR Code reading device will automatically know the best application to open the content.
