Current limitations:
- No VAT handling yet
- SumUp Solo+Printer device not supported

Currently working on adding thermal receipt printing functionality!

I'd love feedback from the community on other features you'd find useful.

ScanPay generates QR codes that instantly trigger SumUp card reader checkouts when scanned.

Simply print QR codes, display them at your event, and attendees scan with their phone camera to pay. No app installation required!

@obsidian.md I would like to update my vault with documents, which I create via python scripts. Does obisidan sync have something like a public API, where I can remotely manage the content of my vault? (without being bound to do it on a specific computer - which works today via iCloud as well).

I was looking for a meaningful integration of bpmn and python code ( partly in order to sort out some nasty state management questions for a workflow), but did not find a good solution. Any recommendations?

Just for curiosity: how does the labeling work with the at-protocol? Is it - technically - some attribute, which you assign to another users profile, which gets pickup up by the Bluesky client?
