Thanks Sbor, with a bit of working too and fro, and getting rid of apps that I don't use that regularly, and sitting with nothing else to do, yes, I got into Google pay, as I said, I took off some apps to give the new one Google pay some space.
Coles one works, now I just have to add the TW one manually.
As I have used Google in the past, so have the suite of Google drive, etc, so it recognises my profile.
Thanks for the tip though, I did play around earlier, on an older Android, and that one was too full of things I needed.
Sorry for the side track/threadjack, will log into my TW account and see if I can get the bar code membership number, I didn't join instore, I joined TW online, so don't have a physical card, but will chase it up this weekend.
But its a pity that under the TW's own system, it does not allow us to keep the bar code on phone, without having to go to another provider, ie, Google pay or needing wifi/mobile data.
Ok, back to the others and see what they feel about this.
Edit (Ps: I do have 2 Android phones).
