I have a hobby project similar to a budgeting app. Ideally, I want the app to prevent me from making purchases I can't afford by monitoring contactless transactions.

This could either be a plugin to google pay (if that possibility exists?) or an app that delegates the payment to Google Pay after validating the inputs (eg, the amount being purchased, time/location etc)

I built a mock-up using Host-based card emulation on Android, but the experience was painful. This question: Payment through HCE implies I could use Google Pay or something similar.

So far everything I've come across deals with requesting payments from the user, to be clear - that's not what this is about. I want the user to use their own card to buy stuff unrelated to me, and the app just permits/denys the purchase.

  • Hey, did you end up finding a solution to this? I had a similar idea but this is currently a blocker – ram02 Aug 19 '22 at 11:00
  • No, I never did. It's a pity, because there seems to be a lot of opportunity for innovation there (that doesn't run through a VC with banking connections) – FrozenKiwi Aug 25 '22 at 22:33
  • I did get a version of HCE passthrough to my physical card, sitting on my desk on a NFC reader, but it was never reliable enough that I felt comfortable leaving my card at home :-D – FrozenKiwi Aug 25 '22 at 22:34
  • Ah it really is a pity. Thank you anyway <3 – ram02 Sep 10 '22 at 10:16
