B2C QR Code Printing data

I have a question about QR Code printing on b2c invoices. Is it necessary for QR code for printing to require all 9 tags or phase 1 QR code(5 tags) data is acceptable for b2c printing?

Salam,
Dear two phases are different and even QR codes are different and once you started phase 2 then you have to use Phase 2 QR code and you will have to discard functionality of phase 1. thanks
