# java-qr-attendance
Just a QR code attendance demo app for my sister's representation, but written in java
## How to run
1. Download java 21 from [here](https://www.oracle.com/java/technologies/downloads/#jdk21-windows)
2. Download the .jar file from the releases page
3. Run the .jar file with `java -jar <filename>.jar`
## Note
**These code for educational purposes only. It is not secure and not optimized for production use.**
_Good luck, sis!_
