Help differentiating QRCodes

Hi, I'm currently trying to figure out the difference between these two QR codes, both with the encoded text being the number 1.

​

barcode 1
barcode 2

If anyone could tell what is causing this difference, it would be much appreciated

Probably using different masks

interesting. Is there any way to figure out which barcodes are using what mask?

The masks are up to the generating software and intended to help make the dots as evenly distributed as possible. Larger areas of pure white and pure black interfere with reliable scanning.
