Networking at events with NFC
Meeting thirty people at a trade fair and remembering none of them the next day is a common outcome. A digital card solves half of that problem; for the other half you still need a system of your own.
Before the event: simplify your card
Review your details in advance: is the title current, which number should ring, which profile do you want them to see. A crowded hall is no place to make those decisions. If you keep multiple card profiles, separate work from personal and leave the right one selected.
In the queue: speed and a fallback
Nobody in a crowd wants to wait. Keep the phone ready and the screen awake, tap, and if it fails move to the QR immediately — trying to debug a tap drains the energy out of a conversation. In a noisy hall a tap is far more reliable than spelling out your name.
The real work: follow up within 24 hours
When you save the contact, write two words in the notes: where you met and what you discussed. A short message the next day built on that note gets far more response than a 'great to meet you' template. A business card doesn't create a connection; it only preserves the chance to make one.
Frequently asked questions
How many people should I aim to meet?
The follow-up matters, not the count. As many people as you can genuinely write to the next day beats thirty you can't place.
Can I leave an NFC tag on my stand?
You can, and it works well. Locking publicly placed tags as read-only prevents anyone overwriting them with other content.
What if my phone dies?
Which is exactly why a few printed cards and a power bank still make sense. Make digital the default and keep paper as backup.
Turn your phone into your business card. Business Card Tap sends your details to another phone with a tap over NFC, and falls back to an on-screen QR code when NFC isn't available. Fully offline, no account.
