How NFC technology is changing contact sharing

Near-field communication makes sharing your details as simple as a tap. Here is what you need to know about the technology powering the next generation of business cards.

NFC chips are tiny, embedded circuits that can transmit data to a compatible device within a few centimeters. When embedded in a digital business card, they allow instant sharing of contact information, links, and more with a simple tap.

The technology is not new, but its application in networking is still evolving. Modern NFC cards can be programmed to share different information depending on the context — work contacts during business hours, personal links on weekends, and so on.

Security is built in. NFC requires close proximity, making accidental or malicious access virtually impossible. And because the data is controlled by the user, privacy remains firmly in your hands.
