Goodbye, paper business cards?

Business cards — once the ubiquitous way to swap details — may be fading in favor of paperless replacements.

These include plastic cards and other objects printed with QR codes or embedded with near-field communication (NFC) chips that transfer info directly to mobile devices.

The Wall Street Journal even talked to a guy who had a chip implanted between his thumb and index finger.

People like digital business cards because they’re:

• Contact-free
• Eco-friendly — 88% of paper cards get tossed within a week
• Easy to update
• Set up to automatically digitize info

But many experts also recommend carrying supplemental paper cards, just in case you run into tech issues, don’t have a smartphone, or plan on doing business in Japan.

BTW: If you like physical cards but still want to be green, these biodegradable paper cards are embedded with seeds that grow when planted.
