    How does the phone confirm the payment without a network? With NFC the phone has a low bandwidth connection to the payment terminal that’s enough to sign the transaction.

    EDIT: I found it. It uses special phone codes that still use the mobile network to do the payment. If I understand correctly it would still not work in places where there’s no reception, like some large buildings or air planes.





  • Deutsche Rentenversicherung should send you an estimate of how much pension money you are going to receive every year. Assume that is optimistic, but a good baseline. I assume the matching program you mentioned is a Betriebliche Altersvorsorge (bAV)? Those usually also tell you how much they will pay you as a minimum, and another estimate based on normal economic growth.

    Chances are that those together will not be enough to match your wage at retirement. So you should plan your savings so you can cover the difference for at least 16 years (which is the current life expectancy at 67 years old in Germany), and overshoot that if you can.
