Anyone having trouble with Optus Cash not working with PayWave?
Especially "CTLESS error 31"
or "no contact less"
errors.Check Settings > look for NFC setting > then tap on advanced settings (which can be found via the tab with x3 dots top right hand of the screen) > “Embedded Secure Element” > ensure “SE SIM Card” is selected.
Make sure these are all true for your phone:
Android Kitkat 4.4 or better.
Check you do no have another payment system messing up Optus one. e.g CBA have a sticker you put on your phone!
Check Phone settings > tap & pay >
ensure that Cash by Optus is selected.
Check in "Cash by Optus" app > settings > payment settings > ensure that under “Contactless on Open” is OFF.
So you don't have to open app to use the PayWave.#OptusCash
