Erik is an amazingly talented designer and we're so lucky he loves working on Cashu apps. His talk is really interesting, I never knew the hidden motivation behind the iMac G3 handle... no wonder I loved my G3 so much!

At @btcplusplus yesterday, Erik walked us through the development of Numo, a Bitcoin POS app powered by Cashu.
A key part of the process has been putting Numo in merchants’ hands and learning from their feedback. These insights have shaped new features and improvements, helping the team understand what a POS needs to fit into merchants’ day-to-day work.
Numo’s development is part of the wider effort across Cashu to make private Bitcoin payments easy to use in everyday life. 🥜

i'll be speaking at @btcplusplus berlin payments edition next week about our approach to building @NumoPayApp.
designing for merchants is very different from designing for end users, but we're working toward a unified payment ux on cashu that makes bitcoin payments as frictionless as possible.
tap to pay in cashu wallets and tap to pay receiving in numo is our first step in that direction.
We rolled this our in the latest version of Numo. Available now numopay.org/releases
Large withdrawal tokens used to be too big for a single QR. v1.9 animates them across frames so any wallet can read it.
That's v1.9! Live now at numopay.org. We're already thinking about the next one, so tell us what you need.

In Berlin for bitcoin++ gets paid?
Don't miss @eriklocalhost talk on Numo: our approach to user testing, the feedback that shaped priorities, and where merchant needs diverged from developer assumptions.
