Each format has its place, but the practical differences matter a lot when you pick what your company relies on.
Paper cards
Fast and tangible — but they run out, go stale the moment anything changes, and can't be measured.
Digital cards (QR)
A public page opened by a QR code, updated instantly with no reprinting, with direct contact links and analytics. The code is stable, so you never re-distribute it after an edit.
NFC cards
BUSMA QR Life offers a physical NFC + QR card: tap it with a phone and it opens the same code page a scan opens — no app. It combines a durable physical card with a flexible digital page.
Which should you choose?
For business, rely on the digital card as your base and add printing/stickers as needed. For personal items, see smart QR stickers & NFC cards.
