CLZ Scanner

A big 2.0 update for your CLZ Scanner app, with lots of changes and improvements:

* Faster barcode scanning
* Reads barcodes in entire camera screen
* New on-screen feedback shows where it "sees" a barcode
* For books: now also "reads" actual ISBN numbers using OCR!
* For comics: now does quick Core check to find out whether it should expect a barcode extension. Which eliminates the need for the AUTO/EXT, so that is now gone
* New app icon to fit the new CLZ branding and style
