Hey everyone,
If you’ve ever worked on a UK healthcare project, you know the headache of generating valid NHS numbers for staging/QA. You either have a messy spreadsheet somewhere, or you’re stuck manually calculating checksums to make sure the UI doesn't throw a validation error.
Even worse—the risk of someone accidentally using a real identifier in a dev environment is a literal GDPR nightmare.
I built SwiftCareID to solve this. It’s a lightweight Chrome extension that:
- Always uses the 999 prefix: Strictly reserved for synthetic test data.
- Modulus 11 Checksum: Generates technically accurate 10-digit IDs that pass all standard validation logic.
- Dev-Friendly UI: Dark mode, Roboto Mono (for legibility), and a smart auto-refresh that pauses when you hover so you don't lose the ID while copying.
- Privacy First: Zero data collection. It only asks for clipboard permissions.
It’s completely free. If you're building in the HealthIT space, I'd love for you to check it out and let me know if there are any other features that would make your workflow faster.
