Therefore, the topic "Building a system to check students by barcode": scanning with attendance applications on Android phones with camera support is a reasonable method, less expensive and easier to use. In the process of researching the thesis, I used the Java programming language on Android Studio, Android SDK was integrated into Android, with the help of Zxing library, I could use the camera of my phone to read the barcode above. Then save the user's real-time data using the cloud-based database service - Firebase. The main features of the application are to create student lists, set events, and scan barcodes above.
