Two technologies dominate digital business card sharing: NFC (Near Field Communication) and QR codes. Both get the job done, but they work differently and have distinct advantages. Here's how to choose.
How NFC Works
NFC uses short-range radio waves to transfer data between two devices held close together — typically within 4 centimeters. It's the same technology that powers Apple Pay, Google Pay, and contactless transit cards. With LincsMe, you simply hold your phone near the other person's phone, and your digital card appears on their screen.
How QR Codes Work
QR codes encode your card's URL into a scannable black-and-white pattern. The recipient opens their camera app, points at your QR code, and taps the link that appears. Your full digital card opens in their browser.
NFC Advantages
- Faster sharing — under 2 seconds
- Feels more personal and impressive
- Works through phone cases
- Great for 1-on-1 interactions
QR Code Advantages
- Universal — works with any smartphone camera
- Can be printed on physical materials
- Works at distance (no need to be close)
- Great for 1-to-many sharing (display on screen to a room)
The Verdict: Use Both
The best approach is to use both. LincsMe gives you NFC and QR code sharing on every card. Use NFC for impressive 1-on-1 moments, and QR codes when you're presenting to groups, printing materials, or sharing with someone whose phone doesn't support NFC.
