FAQ

Got questions?

We've got crisp answers.

No app required on either end. When someone taps your Kardex, their phone's native NFC reader opens your profile in their browser instantly. It works on any iPhone (iOS 11+) or Android (6.0+).
That's the magic. Update your Kardex profile once in the dashboard and every single card you've ever given out — past and present — will reflect your new info the next time it's tapped. Zero reprints, ever.
Absolutely. You control exactly what's visible on your profile. Analytics data is anonymized. We never sell your data or that of your connections. Your profile URL is publicly accessible only if you choose to share it.
Kardex cards are made from premium PVC with a matte black finish — the same material as a high-end credit card. Water-resistant, scratch-resistant, and built to live in your wallet for years. The NFC chip is rated for 100,000+ taps.
