The NFC vCard business cards created with Cardokey are compatible with all NFC-enabled iPhone devices. The application works in real-time, offline, without a database, including airplane mode. It allows users to create contactless business cards, URL links, or social media links on any NFC device, such as tags, ski tickets, metro tickets, or tags.

Cardokey is a practical and eco-friendly solution for exchanging professional information without the need for paper, traditional business cards, or scanning QR codes. It allows users to customize their NFC business cards by adding their own vCard QR code with a logo that can be freely replaced for life. Professionals can also create generic business cards with a free space to attach a repositionable vCard QR code or other important information. This is the principle of eco-design of the Cardokey solution.

It is practical, reliable, and compliant with international standards for data protection and the environment.
