Barcode QR DataMatrix Scanner is a free Android application developed by Generic Co that enables users to scan barcodes and QR codes. The app has a simple interface that is easy to navigate, making it accessible for users of all levels of technical ability. The app's main features include the ability to scan product barcodes, trace LOT numbers, and scan QR codes for advertisements, internet URLs, and name cards. Additionally, users can share scan results with other applications such as email, SMS, and messenger.

To use the app, users should focus on the barcode or QR code in the red line of the barcode scan area. If the barcode scan area is dark, users can turn on the flash by tapping the "Flash icon." However, if the device does not have a flashlight function, the flash function cannot be used. After scanning, users can check the barcode scan result, which can be used to connect or search the internet and share with other applications.

Barcode QR DataMatrix Scanner uses the open-source ZXing barcode library barcode and QR scanner default, which is licensed under the Apache License 2.0. The app is a useful tool for those who need to scan barcodes and QR codes on the go, and it is available for free on the Google Play Store.
