As long the QR shown is a DUITNOW QR, then you can ignore the banner that comes along with it.

1) DNQR + Grab banner = any eWallet support DNQR, yes.
2) DNQR + TnG banner = any eWallet support DNQR, yes.
3) QR + Grab banner = only Grab eWallet.
4) QR + TnG banner = only TnG eWallet.

But one thing I found out i that, if the merchant displays DNQR but it’s their bank account(savings account), you will need to scan using your bank app. eWallets won’t be able to recognize that QR. Dumb me keep scanning the bank account’s DNQR on a eWallet but it kept on saying not recognized.

The original Boost (red label) and TnG (blue label) QR code is still valid. Just use the appropriate ewallet to scan it. Boost scan Boost, TnG scan TnG.

The latest DuitNow QR (pink label) still has weakness. If the DNQR is provided by BANKS , most likely eWallet fail to detect it. If I'm not mistaken, only DNQR by MAE (register as merchant) can accept payment by ewallets successfully.

GrabPay scan MAE DNQR,  successful, NO POINTS EARNED.
Boost scan MAE DNQR, successful, can get Boost Coins.
TnG scan MAE DNQR, successful, as usual (no cashback)

Mind elaborating abit more? I scanned at this non-preferred merchant QR code (not DNQR), $$$ was deducted but no reward points received at all! I thought we could still earn reward points by using GrabPay wallet according to tiers? Am I missing something here?
