Yes. Updates apply instantly. Anyone who scanned or saved your card always sees the latest information — no need to re-share.
Is my data secure?
Cardixn uses end-to-end encrypted storage, row-level security, and never sells your data. You control what is public and what stays private.
Does Cardixn work offline?
Cards are cached for offline viewing once opened, and QR codes can be downloaded as high-resolution PNGs to print on badges, packaging or business collateral.
