We are currently working on our own custom qr code reader apps for various devices.
While we are on that, we would like to recommend these cool qr code readers from Scan, Inc. for your use.
You can get any of them from their respective stores as listed below.
Please note that all qr codes are in the same format anywhere in the world, likewise their readers. So you do not have to download any of these if you already have one. Just any qr code reader would suffice.
