NFC vs Bluetooth for networking: NameDrop, AirDrop, Quick Share or a link?

NFC vs Bluetooth for networking: NameDrop, AirDrop, Quick Share or a link? — Online Business Cards

By Online Business Cards Editorial Team | Published | Updated | Sharing your card

NFC and Bluetooth both help phones swap details, but they do different jobs, and built-in sharing only works between some phones. Here is how each works and when a link is better.

Modern phones have their own ways of swapping contact details. iPhone users can hold their phones together, Android users can send a contact through Quick Share, and almost any phone can send a contact as a file. So why use a digital business card link at all? The short answer is that built-in sharing works best between similar phones and sends a snapshot, while a link works on any phone and keeps showing your latest details. This guide explains how each method works, what the other person actually receives and when to use which.

NFC and Bluetooth: what each one does

The two are often compared, but they do different jobs.

  • NFC works only at very short range. The NFC Forum certifies devices to connect within half a centimetre, extended to 2 cm by its 2025 specification. It carries very little data, but because the devices must be held together, it suits a deliberate start, such as paying or opening a link from a card or tag.
  • Bluetooth works across a room, typically several metres. It is good for finding nearby devices and, with Wi-Fi, moving larger files.

Modern sharing features combine radios rather than choosing one. Apple says AirDrop uses Bluetooth Low Energy to find nearby devices and peer-to-peer Wi-Fi to send the file. Google says its sharing feature, now called Quick Share, picks between Bluetooth, Bluetooth Low Energy, WebRTC and peer-to-peer Wi-Fi depending on what is being sent.

So for networking, the useful question is less "NFC or Bluetooth?" and more "will this work with the other person's phone?". The sections below take each method in turn. We sell digital-only business cards shared by link and QR code; we do not sell NFC cards. Our NFC vs QR code comparison covers NFC cards specifically.

NameDrop on iPhone

NameDrop is Apple's way of swapping contact details by bringing two devices together. According to Apple's support pages:

  • it works between iPhones, and between an iPhone and some Apple Watch models;
  • both devices need iOS 17.1 or watchOS 10.1 or later;
  • you hold the top of your iPhone a few centimetres from the other person's iPhone until NameDrop appears on both screens;
  • you can choose to share your details and receive theirs, or only receive theirs;
  • it shares your name, the phone number or email address you pick, and your Contact Poster, not other fields such as your home address;
  • it only works for adding a new contact, not updating one they already have.

NameDrop is on by default. You can turn it off in Settings > General > AirDrop by switching off Bring Devices Together.

NameDrop is quick and pleasant when both people have recent iPhones. It does not help with anyone using Android, and it only sends the basics.

Sharing a contact card by AirDrop

On an iPhone you can also open your own card in the Contacts app, choose Share Contact and send it by AirDrop, message or email. This sends a contact file, often called a vCard, with the fields you choose. The other person needs to accept it and save it to their contacts.

If your iPhone contact card includes a website field, consider putting your digital card link in it, so anyone who saves your contact can find your full profile later.

Quick Share on Android

On Android, Google's Nearby Share was renamed Quick Share in 2024 and combined with Samsung's sharing feature of the same name. It sends files, photos and links to nearby Android phones, Chromebooks and some Windows PCs. You can share a contact by opening it in your contacts app, choosing Share and picking Quick Share, which sends it as a contact file.

Since late 2025, some newer Pixel and Samsung phones can also send files to iPhones through AirDrop, as long as the iPhone has AirDrop visibility set to Everyone for 10 minutes. Support depends on the model and settings, so it is not something you can count on with a stranger at an event.

Plain Bluetooth

Older phones could pair over Bluetooth and send a contact file. It still works on many devices, but it means turning Bluetooth on, finding the right device in a list and accepting a pairing request. Most people have forgotten how to do it, and it feels awkward in a two-minute conversation.

What the other person actually receives

This is the biggest difference between built-in sharing and a digital card.

  • Built-in sharing sends a copy. NameDrop, AirDrop, Quick Share and Bluetooth all send a set of details at that moment. If your number changes next month, their copy does not.
  • A digital card link opens a page. When someone scans your QR code or opens your link, they see your profile as it is today, with buttons to call, email, save your details or book. If you update your profile, the same link shows the new details.

A link can also carry more than a contact file: your services, a gallery of work, documents, testimonials and, with the Business Plan, booking and enquiry forms.

A quick comparison

Method | Works between | Stays up to date?

NameDrop | Recent iPhones and some Apple Watches | No, it sends a copy

AirDrop contact | Apple devices, plus some newer Android phones | No, it sends a copy

Quick Share contact | Android phones, Chromebooks, some PCs | No, it sends a copy

Bluetooth | Most phones, after pairing | No, it sends a copy

Card link or QR code | Any phone with a camera or browser | Yes, it opens your live profile

When to use which

  • Two iPhone users chatting: NameDrop is fine for a quick swap. Follow it up by sending your card link, so they have the full picture.
  • A mixed group, or someone you do not know: show your QR code. Anyone with a camera can scan it, whatever phone they use.
  • Someone who is not in the room: send your link by text, WhatsApp or email. Our guide to six ways to share a digital business card covers each option.
  • At a stand or event: a printed or on-screen QR code lets several people scan at once without you handing your phone around. See our events guide.
  • When you want to know it worked: a link lets you see activity in your card's analytics. Built-in sharing gives you no record.

Opening a link does not need an app

A common worry is that the other person needs to download something. They do not. Your card opens in the web browser already on their phone. Our guide to what happens when someone opens your card explains this in more detail, including what happens when signal is weak.

Stay in control of what you share

Built-in sharing can send more than you meant to. Before an event:

  • check your own contact card on your phone, and remove personal numbers or a home address you would not hand to a stranger;
  • on iPhone, set AirDrop to Contacts Only or Receiving Off when you do not need it, so strangers cannot send you files;
  • on Android, check who can see your device in Quick Share settings.

A digital card lets you decide exactly what is public, and you can change it at any time. Our privacy guide covers what to put on a public profile and what to leave off.

Which plan you need

Every digital card from us has its own link and QR code, so you can share it with any phone. Brand Presence (£45, one-off) includes your details, social links, documents, gallery, testimonials, templates and analytics. The Business Plan (£90, one-off) adds tools such as enquiries, bookings, contact leads, a card scanner and a CRM. Both are one-off payments, and profiles are built and hosted by our platform partner. You can compare them on our plans, or read how a contactless business card works without any special hardware.

Frequently asked questions

Is NFC or Bluetooth better for networking?

They do different jobs. NFC works at a centimetre or two and suits a deliberate start, while Bluetooth finds devices across a room. Built-in features combine them but work best between similar phones, so a link or QR code is the most reliable way to share with anyone.

Does NameDrop work with Android phones?

No. NameDrop works between iPhones and some Apple Watch models running iOS 17.1 or watchOS 10.1 or later. For Android users, show your QR code or send your link.

What is the difference between NameDrop and a digital business card?

NameDrop sends a copy of your name and one phone number or email address. A digital business card opens a page with all your details, which updates when you change it.

Can I share my contact details by Bluetooth?

Many phones can still send a contact file over Bluetooth, but it usually needs pairing first. Showing a QR code or sending a link is quicker and works on more phones.

Do I still need a digital card if everyone I meet has an iPhone?

It still helps. NameDrop only sends the basics and does not update later. Sending your card link afterwards gives people your services, links and latest details.

Can Quick Share send files to an iPhone?

Some newer Pixel and Samsung phones can send files to iPhones through AirDrop, if the iPhone is set to receive from everyone. It depends on the model, so a link is more reliable.
