NFC (Near Field Communication) cards use wireless technology to share information when tapped or placed near a compatible device, such as a smartphone. These cards can store contact details, URLs, payment information, and more, making them a convenient and efficient tool for networking and transactions.

NFC cards are versatile and can be used for various purposes, such as sharing contact information, promoting a business, accessing digital portfolios, enabling cashless payments, or even linking to social media profiles and websites.

No, NFC cards do not require an internet connection to transfer data. However, if the data on the card links to online content, such as a website or app, the connected device will need internet access to view it.
