I don't run an OS on my phone or laptop that could run a proprietary banking app in the first place. Can't be inconvenienced if you don't know what convenience feels like in the first place.

• Convenience, no need to waste time and car fuel going back and forth to the bank all week as i get a lot of cheques and i can just deposit straight after reception from my phone itself

• Mine put new ones in all year round as its not really a bank, kind of the same but it's a "caisse populaire" in my language.

• Not really. If they offer it to mobile, they'll offer it to computers always.

• 2FA
• Some banks I use require I aprove transactions on my phone when I am paying this online
• One bank I use has tap to pay on the app instead of relying on Google Wallet

I live in the Netherlands, where there's a QR-code-based payment method called iDeal, which you need a Dutch banking app or little code machine thing to use. With my bank, at least, there are a few things you can do with the website that you can't do with the app, but for day-to-day use the app's fine.

They are important.

I need to use them on the go so it's a must have.

NFC payments

Works fine on lineage os
