All about QR Code


Ever wondered how you can pay bills, send or receive money, scan for identification, or scan for digital menu cards just by scanning a code? QR codes are all everywhere, but what exactly are they?


QR Codes: What and How?


Quick Response code (QR code) is a trademarked term for the most popular sort of two-dimensional barcode accessible by smartphones. Whenever users scan a QR code, the recognition software on your smartphone decodes the horizontal and vertical structures of the matrix and converts them into a sequence of characters.


The stored information in QR codes is encoded in a grid pattern of black dots and empty spacing. With the use of imaging equipment, such as a camera or a scanner, these structures can be scanned and transcribed into human-readable information. However, currently, the most frequent approach to scan QR codes is to utilize your smartphone’s camera with a QR code reading app.


QR codes can be used for a variety of purposes:


For e-learning purposes:


Learners can scan QR codes to easily access video or audio lessons from their books or coursework, allowing them to go deeper into the subject. This combines the best of the two, giving them a genuine book to learn in while also adding a digital dimension.


For Retailers:


Consumers or customers can quickly pay for groceries or stationery using QR codes, while business owners can receive money immediately into their account in a matter of seconds, making it the most important no-contact money transfer method during the ongoing Covid outbreak.


For Restaurants:


Gone are the times when regular menu cards were handed out separately or when a table of four was served with only one single menu card. People can scan QR codes to acquire their menu cards, Place their order, make their payment, then wait for their food to arrive efficiently.


For Events:


Event marketers or organizers might provide participants with a QR code to scan, which would display the event location, maps, registration eligibility or registration portal, discounts, or offers.  Further, the data gathered from the scans could be used to estimate the number of attendees.
