QR Card

07 Jun 2024

I made a thing!

Okay, it’s nothing big, but it was a nice, quick turnaround, one feature product.

I have a friend who sells a few of his own products in local markets, and he had a bit of a problem. He wants to accept cashless payments, but he has a revenue of a kid’s lemonade stand, and he does it more as a hobby, so he doesn’t want to pay any 3rd party fees.

Since almost everyone around has a mobile banking app with QR code instant payment, I of course immediately suggested “hey just generate QR code in your banking mobile app?” you will immediately see if you received the payment. But this has a few problems:

his mobile banking app is clunky, the QR creation dialog is hidden behind 4 clicks
you need to do a FaceID check every time
you can’t let 3rd party, like a family member, handle it, since you automatically grant them complete access to your bank account

MVP idea

What if we extracted the QR code generation to a standalone app, that would not have access to your bank account? You could have it open in a tablet, with your mobile banking installed there, so you could see the instant payment notification, so even 3rd party users could confirm the payment was made.

Few moments later:
