Unless you’ve dabbled in the mystical arts of QR code and barcode scanners, their inner workings shall forever remain a mystery to you.
Barcodes: the OGs since the 1970s. QR codes: the late bloomers since 1994. But wait, who stole the limelight? With the rise of mobile devices, QR codes have finally come to life. These visual data-storing symbols are like the cool kids in town. They track inventory, identify products, and even rock mobile marketing. However, barcodes and barcode scanners still play an important role in everyday life.
Everything You Need to Know About Barcodes
Barcodes are like fashionable zebra stripes – a stylish arrangement of lines and spaces that speak the language of numbers and letters. When a barcode scanner does its magic, it deciphers the pattern and transforms it into computer-friendly data. It’s like a secret code between machines.
There are different types of barcodes, such as EAN/UPC codes commonly used for retail products, Code 128 for shipping labels, and Codabar for libraries. They all work in a similar way but have different formats and purposes.
The Evolution of QR Codes
QR codes, on the other hand, can store more information than traditional barcodes. The QR codes are square-shaped, featuring black and white modules arranged in a specific pattern. Upon scanning with a QR code reader, users are seamlessly directed to a website or app that provides additional information about the code.
Originally developed for the automotive industry, QR codes have gradually gained popularity across various sectors owing to their versatility and capacity to store extensive data. They are now used in advertisements, event ticketing, contactless payments, and even COVID-19 contact tracing.
How Do Scanners Work?
Barcode scanners use a light source (usually a laser) to illuminate the barcode and a photosensitive detector to capture the reflected light. The pattern of light and dark areas is then decoded into binary data, which is translated into readable characters by the computer.
On the flip side, QR code scanners employ image sensors to spot the captivating contrast between the black and white modules within the code. Once captured, they transform it into a captivating alphanumeric string that can be effortlessly deciphered by the device.
Barcodes and QR codes: the dynamic duo that have turned data collection, storage, and retrieval into a tech-tastic revolution. With constant advancements, they’re like the superheroes of innovation, always evolving and unleashing new powers.
With portable barcode scanners from ScanAvenger and the like, businesses can now easily collect and store data for inventory management, sales tracking, and other purposes. Mobile QR code readers have also made it possible for individuals to access information quickly and efficiently on their smartphones.
Whether you’re reading this as a savvy shopper or a sharp entrepreneur, dive into the inner workings of these tech wonders and uncover their boundless possibilities. Who knows, you might crack the code to a brilliant new use for barcodes or QR codes. So, next time you scan, take a pause to marvel at the hidden magic fueling this digital wizardry.
