How NFC business cards actually work

An NFC business card is a credit-card-shaped piece of plastic, metal, or PVC with a tiny chip and a copper antenna embedded inside it. When someone holds a modern smartphone within an inch of the card, the phone reads what's on the chip and acts on it. There is no battery, no Bluetooth pairing, and no app to install on either side. The card is essentially a tiny URL written into a chip — and the phone's built-in NFC reader is what does the work.

The chip is tiny. The link is what matters.

Every modern NFC business card stores a single piece of information: a URL. When you order a Got It Tap card, we encode it with your gotittap.com link — for example, gotittap.com/c/your-handle. That URL points to your live profile, which is hosted on our site. The chip itself is never re-written when you change your profile; your profile lives online and the chip just points at it. That's why you can swap a job, a phone number, or a photo and the same physical card keeps working.

What happens during a tap

Here's the exact sequence when someone taps a Got It Tap card:

• 1. NFC handshake. The phone's NFC reader detects the chip's antenna and pulls the URL off it in a fraction of a second.
• 2. Notification or auto-open. On a modern iPhone or recent Android, a banner appears at the top of the screen with the URL. The tapper either taps the banner or, on most newer phones, the URL opens automatically.
• 3. Browser loads your profile. Their phone's default browser fetches your live profile — your photo, your contact info, your social links, your portfolio.
• 4. Save to phone. From your profile they can save your contact card, add you to Apple Wallet or Google Wallet, text or email you, follow you on socials, or tap a payment link — whatever you've put on your profile.

Total time from tap to profile-open is usually under two seconds. The tapper does not download anything. They do not authenticate. They do not give you their information unless they choose to.

Why no app is required (on either side)

NFC reading is built into the phone hardware. iOS has supported background NFC tag reading since iOS 14 (iPhone XS and up). Android has shipped NFC support in mainstream phones for over a decade. Because the chip's payload is a standard URL, the phone treats it exactly like any other link — it just opens in your browser. There is no app to install, no QR camera to point, no Bluetooth pairing dance. Holding the phone near the card is the entire interaction.

Phones that work — and phones that don't

Practically every smartphone made in the last five-plus years can read an NFC business card. iPhone XS and newer on iOS 14 or later support automatic background tag reading. Older iPhones (7 through X) can read NFC tags but require the user to open the camera app or use Control Center first. Almost every Android phone manufactured since 2019 supports NFC out of the box. The rare exceptions are budget Androids and a small number of older models that shipped without NFC hardware.

Where the profile lives

Your profile is a normal web page hosted at gotittap.com. It's mobile-first, fast, and has Add to Apple Wallet plus Add to Google Wallet buttons built in. When a tapper saves your card to their wallet, your contact lives on their phone next to their boarding passes and credit cards — they can pull you up again even when they don't have your physical card on them. That's the part paper cards can never do.

What changes vs a paper business card

A paper card is a one-way handoff. They take it, you hope they keep it, and 88% of paper cards end up in a drawer within a week (Statistic Brain). An NFC card flips the handoff — you give them a physical object that puts you inside their phone, which is where their contacts, calendar, and wallet already live.
