The QR code scanner is a handy piece of technology as it is used for smart phones, tablet PCs, electronic reading boards and other devices. The application Barcode Scanner is a free Android application, in the open source project ZXing, which enables an Android device having digital reading hardware to scan various barcodes or 2-dimensional 2-D barcodes and then retrieve the stored information. This data is then sent to the applications, for usage and display. A QR code scanner can decode these codes and deliver this information into an application on the user’s phone.
QR codes are short for’QR codes’ and are an internationally accepted way of encoding data and enabling devices such as smart phones or tablets to read these codes. These codes can be used to store any information on a digital medium, including maps, emails, documents etc. Currently the leading systems are used for personal digital assistant (PDA) use, retail, industrial, corporate and travel purposes. The scanning software must have an inbuilt memory that stores the patterns and images onto the QR code image, upon which a user can then scan the QR code to read the information. This technology is fast becoming popular in mobiles because it allows a user to make instant smart phone calls from their PDAs without having to hold the PDA next to their ear.
As the QR code scanner has been developed for use with mobiles, they are now being adopted more by the public in both the corporate and public sector. This is because of their ease of use and portability and also because they are cost effective. Many businesses see the value of using this technology, as it not only makes communication more convenient but also reduces the time spent on printing receipts, for QR code scanner.
Using a QR code scanner is quite simple. Simply place your document or image on the scanner, press the start button and then scan the code. A prompt will appear to indicate which pattern of the QR code you are trying to decode. Once the image has been decoded, the relevant information will usually appear within a matter of seconds.
QR code scanners are usually connected to a computer via a USB cable to upload the data into the computer. They can also be directly connected to an LED display screen. A screen will pop-up asking for the relevant code to be decoded, so all one needs to do is point the scanner at the target document and press the start button. It is also possible to select to view a preview of the decoded information, so the user will know exactly what they are going to see upon scanning the code.
One of the many advantages of having a QR code scanner is that it enables a business to save money on printing receipts. As people continue to grow increasingly wary about accepting electronic payments, the need for receipts will likely reduce. A business can use the scanner to create a unique code that has the recipient’s contact information on it. This information can then be stored in the device or uploaded into a website for easy access.

The scanner functions as a reading device that allows the user to see the current time in several different modes – alarm clock, calculator, game and more. The iPad can also connect to a wireless network, meaning that all of the contacts stored on the device can be checked as needed.

Some can even create custom logos as well as business name labels. When shopping around, make sure to take a look at the available options. Also check out the price.
