Hii just wanna ask what the best arduino materials for qr code scanner for offline hope you see this message, it's for our capstone research about arduino-based student verification system

If you use an external QR/barcode reader module then you can access the data on an Arduino board using its UART.
SparkFun have a tutorial here:

and a video of it being used via USB here:
Thankyou sir. can it be use in database on xammp and can display information in vb.net sir?
The scanner module scans and decodes the QR code in front of it and outputs the data on a serial connection (USB / UART).
How you read, store and process that data afterwards is up to you. You just need to trigger the capture (manually or via code) and then read the captured data returned over the serial connection.
In this case you don't need an Arduino as the scanner module could be connected directly by USB to a computer (similar to the YouTube video linked previously) and then by running an instance of VB.NET. However the likes of an Arduino may be useful if you want to use sensors / indicators to trigger the scan and give user feedback along with logging captured data to SD card for offline use.
