The Barcode Scanner: How It Makes Life Easier

Barcodes & Barcode Scanners

A barcode scanner works by reading barcodes. To fully grasp the way these scanners work, you should first understand what barcodes mean. A barcode is a readable code made up of parallel lines – usually black lines on a white background – and a string of numbers at the bottom. These lines and numbers contain readable data that can be scanned by the barcode reader and relayed to a display screen. The parallel lines are the machine-readable part of the barcode, and the string of numbers is known as a Universal Product Code (UPC). Barcodes store any information programmed into it, and they are on practically everything, even in emails and product descriptions.

A barcode scanner reads the information coded into the barcode and converts it into text for display. There are different types of barcode scanners that can be used for various functions depending on your type of business. They are very popular in supermarkets and grocery stores.

Operating a Barcode Scanner

Many business owners have turned to use barcode scanners in their day to day businesses. Once set up, these scanners have straight forward applications and are quite easy to operate. The barcode scanner reads a barcode by illuminating it with a red light or laser, and then its sensors detect the reflected light, generates a signal, and decodes it. The decoded signal is interpreted and converted into text on the display screen.

This may sound like a long, complicated process, but it isn’t. It takes nano-seconds for a scanner to read a barcode and display its information. Operating a scanner involves placing the scanner in front of the code – or vice versa, depending on the size of the scanner used.

However, whether it is used for inventory and stock management, file sorting, patient identification, flight confirmation, or item checkout, the reader has to be set up for the particular operation before it is used.

Types of Barcode Scanner

There are different types of barcode scanners. Depending on its use, each barcode scanner operates in a unique capacity. There are pen-type readers which use a light source on the tip of a pen to read the code, as well as laser readers, which use a laser beam to read the scan code. These types of readers are hand-held, quite popular, and perfect for reading items from a distance. 

Other scanner types are Charge-Coupled Devices (CCD readers) and omnidirectional scanners. The CCD readers, also called LED readers, use several light sensors to scan code, and relays the information to a display computer or screen. Omnidirectional scanners are more advanced and efficient readers, and they can even read crumpled or torn barcodes on items.

Lastly, there are camera-based scanners that employ image processing features to read different types of barcodes and QR codes. An example of a camera-based scanner is a QR scanner installed on a smartphone.

Using Scanner Features to Make Life Easier

You no longer have to spend long hours writing down stock information or searching for medical information or typing item numbers by hand to get their prices. Barcodes and barcode scanners help save all that time and stress. Scanners are fast, accurate, reliable, and efficient. These features are essential in all industries, and having a scanner that can give you all these makes life much more comfortable. With scanners, store managers can take stock faster; asset management companies can compile reports more accurately, cashiers can checkout customers more quickly, make online shopping purchases speedily, and so much more. Using barcodes and barcode scanners in hospitals has made medication administration easier too. A quick scan does everything that filling out a report used does.

In the world we live in now, there is a barcode or QR code everywhere you turn – public parks, airports, and even schools. With a simple QR code scanner app like QR Code Reader, you can track an order or confirm the components of a sealed container.

Having a simple barcode reader in your business or with you can make a world of difference. Barcode scanners are not just business tools, but they are also handy life tools.
