QR Code and Barcode library

[Manuel Manhart]

Hi,

I want to build an app, where you can scan existing barcodes (like on books or other products) as well as create your own qr code or barcode.

What I've found so far are libraries that can do one thing of the following: create a qr code, read qr codes, create barcodes, read barcodes.

What I haven't found (but would like to have / use) is one library that reads a code regardless if its a barcode or a qr code.

Anybody knows such a library?

Thanks upfront for any answers.

Hi Manuel,

As far as I know, you are best off with a hardware barcode scanner, you can have those already from 24 euro off. A reader that would scan QR too, might be a bit more expensive, but will probably start at 35 euro. 

There are a couple of libraries that can read QR, or barcode's using the cam of a computer/phone. Those are nice for simple things but are terribly slow and unpredictable. When you need to scan any real volume, a dedicated hardware reader is still the way to go.

If you want to stick with cam, XZing is a good place to start (not JS, but you can find more there). Based on that there is QuaggeJS

Hope this helps

Regards
