All good.

The rfid can work trough fabric. So a shielded wallet is a smart choice. Technically someone can make you pay by tapping your pants with a terminal device. Does this happen allot? No not really. But technically possible and more likely when more people use tap.

Here there is a maximum amount that can be paid with only contactless payment without a PIN code. If the price is higher a pin prompt will show up automatically (max $25,-) If you pay more things in a short time with the rfid than the pin prompt will eventually show up. So an unlimited amount of low payments isn’t possible. (Do check your bank for these details.) So when you lose your card your account can’t be drained. (Unless you have less than the minimum amount on your account)

Phones can also be setup as a contactless payment method, and would physically work the same. With the benefits of having a stronger signal, and being locked behind your phone lock (facial recognition or whatever.)

Yes and no. Your water supplier can alter the pressure of your water. This happens, for example, when there is a water shortage. But mostly yes.

FAQ from https://github.com/tuyafeng/Via#faq

Which rendering engine does Via use?

Via uses the built-in WebView renderer included on the Android platform. On Android 5.0+ devices, the WebView implementation is usually Android System WebView (com.google.android.webview), you can update it in the Play Store for a better browsing experience. If you want to know the current WebView implementation and version of your device, you can click “Settings - About” in Via and tap on the Via logo to get the debugging information which contains the WebView information.
