How Digital Business Cards Reduce Your Carbon Footprint
| Technology | Lets Connect
Every paper business card has a carbon cost: tree pulp, ink, energy, and shipping. Digital NFC cards eliminate the entire cycle — zero emissions per share.
Both NFC and Bluetooth enable wireless data exchange, but they're built for different jobs. For business card sharing, NFC is the clear winner.
