Can Detect ASCII Characters

This app is one of the only barcode readers on the App Store I’ve found that can detect ASCII characters. This is extremely useful for ensuring barcodes have the proper encoding. With all the other big name/reviewed apps you’d be clueless. Love this app.

Great tool for analyzing barcodes

Agree with reviewer ChrisG2023. This is one of the only iOS apps that actually shows the embedded data of a 2D barcode. Very helpful

Exactly what I needed

This app is perfect. It is simple and is exactly what I needed to verify that generated barcodes were correct. Well done.
