An NFC vCard is a digital business card embedded with NFC (Near Field Communication) technology. This allows contact information to be shared quickly and effortlessly by simply tapping the NFC-enabled card against a compatible smartphone or device.

NFC vCards work by utilizing NFC technology, which allows data to be transferred between devices that are close to each other. When an NFC-enabled smartphone is brought near the NFC vCard, the phone reads the embedded information (such as name, phone number, email, and address) and can automatically save it to the phone’s contacts.

Most modern smartphones are equipped with NFC technology and can read NFC vCards. This includes many Android devices and iPhones (iPhone 7 and later models) with NFC capabilities. However, it's always good to check the specifications of your device to ensure NFC compatibility.
