NFC payment bank-app doesn't work. - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello all,
I use a dutch bank-app for wireless nfc payments (ASN betalen). It worked fine on my Nokia 7 plus, but it doesn't on the Mi 9t (MIUI 11.03.0). The app says that there are apps active that control displaybrightness and I have to turn those off otherwise it won't work. Then it directs to the 'display over other apps' settings, where the payment-app isn't listed. NFC itself works, I could pay with it until I had to use my fingerprint or pincode for verification. The app doesn't show then, so I can't give any verification.
I disabled automatic brightness and disallowed all the apps at 'display over other apps' (the payment app isn't there). I reinstalled the app several times, I gave the payment-app all the possible permissions, but it still doesn't work.
Does anybody please have some ideas I could try?

Try uninstalling all apps but the bank app.

Is your wallet set on HCE under nfc/...?

It's set to the wallet of my simcard. But I don't think that's the issue. NFC works, I even managed to pay with it. The app just doesn't show when I need to use a pincode or fingerprint for verification.

First disable fingerprint & MI Security overlay & automatic brightness. Check: NFC on, HCE Wallet, default app "Betalen".
Then open your payment app (ASN Betalen) before you hold the top of your phone (MI 9) to the terminal.
It should work.
Now you can try to able fingerprint and other overlay apps (Mi security and/or brightness). Or don't change if it works

[Q] Google Wallet odd error.

So I have scoured the internetz for the same problem I am having and I cannot seem to find it. So I guess ill ask here.
1. I rooted my phone and installed TWRP
2. Tap pay was not working so I uninstalled google wallet, cleared the cash and data and re-installed.
3. Authorized tap pay and now the wallet app is working fine.
4. Problem.. It does NOT activate when I use the NFC at the register. Nothing happens.
I have also tested NFC. All other NFC functions are working properly, but when I pas the NFC by the reader at the register it does not activate the google wallet app and request the pin.
I am completely boggled. I meen I love google walled but I love TiBu even more.. soooo and theories?
Thank you in advanced.
P.S. Yes, I have used wallet at the same location previously to rooting my phone. It is not there reader. There reader actually buzzes as if it detected my phone but no info was received.
- Google Wallet is a fickle thing and editing certain system files after rooting will disable its NFC abilities, most notably build.prop.
- If your phone is locked, you have to unlock it before tapping the retail reader. My phone is almost always in my hand so I'm unlocked with Google Wallet already open past the pin screen.

Settings force closes when accessing NFC option.

For the past two days I have been experiencing force closes of the Settings app whenever NFC and Payment is selected, due to this I'm currently unable to turn on the NFC option in order to use Android Pay and (or) Samsung Pay. Has anyone else been experiencing this or might have some advice on what the issue may be?
Thanks

Have you disabled any apps? Maybe clear data on the NFC app?

Thanks for the advice, I'm currently using Package Disabler Pro and I had several apps disabled although I had unmarked the NFC service it would still be disable, I had to uninstall the app and reinstall, un-check NFC service and was able to access NFC and Payment. Guess it was an error on my side.

Can you use the in-display fingerprint reader for banking apps?

So I know you need to use the Ambient Display / wake on tap to use the fingerprint reader.
But can you use it for regular fingerprint apps, like a banking app?
I tried finding information about this in Youtube comments and whatnot, but no one replied.
Thanks!
The banking app I use along with other apps that use fingerprint work fine with a fingerprint.
It works with my 2 banking apps.
Also works with other, non banking apps...
Works for me as well, ABN Amro in the Netherlands.
Yes. Works just fine using Numbrs.
It works exactly the same as every other fingerprint reader, so yes.
I can relate. With my Samsung Galaxy S7 my Wells Fargo app would allow me fingerprint to sign in option, not anymore on the OP6T. But on the Cash app, to deposit money it presents the option for fingerprint yet oddly enough only receiving - not when sending money
Yes, works fine
Works with my PNC, Paypal and also MyBuick app
That is very weird. Maybe the app is too old? Or OnePlus has to fix the firmware?
Working on all four of my bank apps
So it was actually well hidden in the settings but I got it to work lol. Thanks for the doubt guys.
Working well with all my bank apps (CapitalOne, BoA, etc)

Works with Barclays in the UK also(Banking and PingIt).
Works fine with USAA, CapitalOne, KeePass, Authy and everything else I've used it for.
Works with Chase, JP Morgan, Citi, American Express, discover, and google pay.
. Yes, you can use fingerprint reader for logging in to your online banking account. Have it set up before you download a banking app, once you go through initial login /password /secret words, etc, a pop up window will ask you if you want to use fingerprint for future logins. Tap yes of course and it should work. Same is for PayPal, ebay for instance
Like everyone else said it works just like any other fingerprint scanner.
PayPal and Bank of America works fine with it.
@Elloco305 the phone settings or the bank app settings?

Google Pay Issue

I don't even know if it's an issue: when i try to use Google Pay in store (NFC) it returns with an error asking for my finger print(phone already unlocked), resulting in an error as well on the vendor side(machine). I have to put the finger print and google pay app asks to get closer again and after all of this, it works. I know that google pay is supposed to work without asking for finger print, just using the phone unlocked witch i did.
Do u people have to do that or it just works (without the extra authorization)?
PS: I did a deblot, but I already reinstalled all the Samsung pay and pass stuff even guessing that it didn't cause the issue.
Thanks in advance.
did you set it as default? i have a pass which i need to set google pay as default. otherwise i would only use samsung pay.

Yeah, its set as default. When you use google pay, even the phone already unlocked, it asks you to put the fingerprint?

never really use google pay for payment before, only passes. for passes, never request for fingerprint or anything.
i once installed an app somewhere in the internet and many times, it would ask for fingerprint. uninstalled it btw.

privacy questions on my op5

Hey all
My setup: twrp, magisk, lineageos 16,
I see that Google installed its Bluetooth contact tracing app or system or whatever it is called on my op5 without my consent.
Other than completely removing Google services from my device, is there a way to remove that contact tracing component from my op5?
When I disable Bluetooth in the settings, does it completely disable it, or does Google or any other applications have a way to bypass the disable and keep using it?
Does this disabling of other sensors (WiFi network gps) apply as well, can be bypassed by Google or other applications?
Regards

Google doesn't need your consent, because it is not your device. It theirs, if you have Gapps installed. And yes, Google is able to manipulate gps/bluetooth/wifi also without your 'consent'. It is simple: no Gapps, you control the device; yes Gapps, Google controls it.

If you mean the COVID Bluetooth tracing, that is only active if your country's government is cooperating with Apple+Google for this. You'd need to install your government's app to activate that feature, otherwise it is disabled.

That is not true. If that would be true, Google would be dead by EU laws already.

It is true. EU privacy laws don't deal with the way Google manages your device, only with consent regarding user data.
If you have Google Services, Google is the administrator of your device: it can delete/install anything it wants to without your consent, which by the way, you have already provided by installing Google Services.
Thank you guys for your responses.
I am talking about the covid Bluetooth activation.
Regards
