QR Reader is a new app from the open-source project ZXing, enabling an Android device with non-intrusive imaging hardware to scan QR codes or 2D bar codes and extract the relevant information directly from the flash memory. This functionality is similar to that of the popular Amazon Kindle’s QR code scanner. However, the main difference between the QR Readers available in the market and the one from Amazon is that the latter can be used on smartphones. Despite this, the functionality is not identical since it depends on each type of reader’s memory availability. This article discusses the main differences between the two devices and offers some advice to buy the right QR Reader for you.
As the name implies, the QR reader for smartphones operates with the help of a QR Code. A QR Code is a shortcode composed of eight-bit numeric characters that are denoted by long lines. These are arranged so that they form a triangle when viewed from an upper view and a square when scanning from a lower perspective. To decode the code, the smartphone needs to access a special database that stores all known QR Codes. As mentioned earlier, there are several different types of codes, and hence the smartphone needs to select the correct code for the call to action.
Apart from the database, several other factors determine whether the barcode scanner is the right choice. The first factor is the scanning speed of the app. As the name suggests, the faster the app is, the faster the information can be accessed. To ensure fast reading, the QR Reader must access the data from the QR Code very quickly.
The second factor is the compatibility of the app with various operating systems. While there is no compulsion for the app to run on every OS, most users prefer to finder patterns available on the most popular OS. As a result, users need to go through the list of QR codes to find the one that matches their requirements. This way, the user does not have to spend extra time downloading and installing the app on different devices.
Many other factors affect the choice of the best finder pattern. For example, some directories have strict guidelines while requesting a QR code, and as a result, the quality of the codes produced is deficient. Hence, users need to take extreme care while choosing the directory. Another factor that affects the choice is the price of the QR codes. Some websites offer high-quality QR codes at extremely competitive prices.
On the contrary, some websites offer codes at reduced prices because of bulk orders. Such websites usually have a huge database of barcode scanners that can scan all types of barcodes. Hence, you will be able to find a suitable QR reader for your business very quickly. Also, if you want to test the app’s functionality before purchasing it, you can always request a demo scan.
