Today I tried to install one more rMQR code scanner app for Android phone from Google Play.

The SCANDIT app supports rMQR code for scanning.  The app is available as demo version capable of scanning all types of barcode.

you have to select ANY CODE option for scanning rMQR code. The scanner is able to read the 150 digits of Pi code without any errors.

The above is the scan result of Pi value for 449 digits split into 3 groups. 

Compared to QRQR barcode scanner app, there are some differences observed.

• SCANDIT app is capable of reading the code ONLY when the background is WHITE. But QRQR app is able to read the rMQR code with any background color. QRQR app is capable of reading the RED, GREEN and BLUE background rMQR codes easily.
• Similary the SCANDIT app is NOT capable of reading the inverted rMQR code. So the scanner app is NOT capable of reading the BLACK background with WHITE code. But QRQR app was able to read the inverted rMQR easily.
