Fact and need to watch more for updated cards which are acceptable in DF for QR codeNo that's not the case as per my understanding. DreamFolks is a lounge service provider same as Diners Club International or Priority Pass or Lounge Key. The cards working for this method are the ones which have tie-up with DreamFolks (as we are using Web Access provided by DreamFolks). For other cards regardless of card network (example IndusInd EazyDiner on Visa) it throws error.
