Everything you need to know about Sigma Cards, NFC technology, and shipping details.
NFC stands for Near Field Communication. It's the same technology used in Apple Pay or contactless bank cards. Inside each Sigma Card is a microchip that transmits a secure link when tapped against a phone. The phone automatically opens the user's digital profile dashboard on the web browser.
No app or software download is required for the person scanning or receiving your details. They simply hold their phone close to your card, and your digital business profile will load natively in their default web browser.
Nearly all modern smartphones (released after 2018) are fully compatible. iPhones (XR and newer) have NFC enabled by default. Android devices also have native NFC toggles. For older devices, every card includes a unique printed QR code on the back that can be scanned using any camera app.
No, there are no mandatory subscription fees for individual profiles. The card purchase covers the physical smart card and lifetime digital profile hosting. Organizations/B2B admins can opt for flat annual plans to access multi-user management consoles and advanced enterprise features.
Yes, security is a priority. If you lose your card, simply log into your dashboard and toggle your card status to "Inactive". This blocks any browser redirects instantly. When you order a replacement card, you can easily link your existing profile details to the new chip within seconds.
Join thousands of professionals, startup founders, and enterprise organizations who trust Sigma Cards to close connections instantly.
