Smartphone barcode scanning apps are changing the way people shop. Shoppers can scan an item's barcode using a mobile device's built-in camera and a barcode scanner app. This provides shoppers with all kinds of useful product information to help them make a more informed purchasing decision.

To human eyes, a barcode is a square or rectangular image or label found on the side of almost every product sold today. It seems to consist of nothing more than a series of parallel black lines of differing widths and spacing. In reality, this seemingly random black and white design contain a wealth of information.

The barcode is actually a machine language. It visually represents data that can be read by a device like a barcode scanner. Some of the information contained in the barcode on a box of food can include-

  • Product name
  • Price
  • Product specifications (size, color, type, etc.)
  • Manufacturer
  • Production time & date
  • Expiration dates
  • Ingredients
  • Nutritional information

Barcodes have been around since 1951! However, they didn't really begin to catch on until retailers began to adopt automated checkout systems. Today, you'll find a barcode label on almost every item you purchase in-person or online.

In addition to speeding up and simplifying the transaction process, barcodes provide many other advantages, including-

  • Eliminates pricing errors
  • Data is available immediately
  • A barcode scanning system is easy to use and learn
  • Barcodes are easy and inexpensive to generate and print
  • Provide better sales and inventory management
  • Barcodes can contain a wide range of data

There are two kinds of barcodes- one dimensional (1D) or linear, and two dimensional (2D). 1D barcodes are the ones with the lines, such as a UPC barcode. 2D barcodes like QR codes consist of an arrangement of geometric shapes.

Up until recently, you needed a barcode scanner device to read a barcode. Now you can download a barcode scanning app directly to your smartphone. Barcode scanning apps have created a whole new way of shopping

What Kind of Information Can a Barcode Scanner App Reveal?

the importance of barcode scanner apps 1634340051 2384.png
With a smartphone barcode scanning app, the device's camera functions as a scanner. It reads the data and sends it to the app. The app decodes the data and presents it in a format that's readable by humans.
A barcode is basically an image encoded with information. What kind of information a barcode contains depends on what kind of object a barcode is printed on. For instance, the barcode information found on a cereal box is different from the data found on a driver's license.

While all sorts of information can be encoded into a barcode, how much depends on the type of barcode. 1D barcodes, like the UPC codes, are limited in the amount of data they can contain. 2D barcodes, like QR barcodes, can contain much more information.

UPC and other 1D barcodes usually only contain between 8 - 25 characters. This is due to the limited space available on the barcode label. Except for special characters, any type of data can be stored in a 1D barcode.

2D barcodes like QR codes can hold between 1,000 - 2,000 characters. Unlike 1D barcodes, they can use any character and contain hyperlinks. 2D barcodes can encrypt data both vertically and horizontally.

What actual information the barcode contains depends on the person creating the label. Sometimes it's just a bunch of identification numbers. In other instances, barcodes can contain information that describes a product's specifications and more.
