Hey there, @Arv1956 -
Welcome to the Community!
To start, I want to check if you're using an iPhone or Android device to take the Tap to Pay. I've hyperlinked Support Articles for steps on both. I would recommend double checking the steps, making sure your device & app are up to date, etc.
If you gives these a try and still see this error, please let me know! I will be happy to circle back with you.
