NFC is found everywhere these days from credit cards to door locks, but must importantly: your smartphone! With a few simple steps and relatively low costs you can create a digital business card that uses NFC and can be read by a smartphone to transfer contact information. This high-tech solution makes exchanging your contact information not only fast and easy, but also makes you look very cool!

(this Instructable was made for the TfcD course @ TU Delft)

Step 1: Step 1: Preparation

Creating a digital

business card is quite simple and doesn’t have to be very expensive. Here’s what you need:

  • Some NFC tags. We got ours from nfc-nederland.nl, but you can find them on Amazon or DealExtreme as well. Be sure to check how much memory you need to put all your information on one, since NFC tags have a REALLY small storage capacity (think bytes!).
  • A smartphone with an NFC chip (most current cell-phones have one).
  • An App for reading and writing NFC chips. We used NFC Tools, since it allowed us to create a command that opens a link on your phone with a relatively small number of bytes.

Step 2: Step 2: Set-up Your NFC Chip

First, check to see if you’re NFC chip is empty and ready for writing. Ours came with a link to the App we’re using on it. Simply turn on NFC communication on your phone and hold the chip to your phone to see what’s on it.

If yours has some data on it as well you’ll have to format it before you can use it.

Step 3: Step 3: Upload Your Contact Information

Now select the information you want to put on your NFC tag. Since ours couldn’t contain much data we decided to simply put a link to our LinkedIn account on it. But if you buy a bigger NFC you can upload your entire contact information on it, so it is immediately added to someone’s phone.

Step 4: Step 4: Create Your Business Card

Create your business card using Illustrator or whatever program you feel comfortable with. Make sure you think about where you’re going to place your NFC chip. You can leave one side unprinted or simply stick it between two layers, like we did.

If you’re not feeling too sure about your design skills you can simply download our template! (you can print them on A4, one-sided)

Step 5: Step 5: Get Connected!

You can now use your card to quickly hand over your contact information and expand your network! Simply swipe your business card next to someone’s phone and put it back in your pocket or hand them out like high-tech candy!

<p>And here's my goofy business card. A few typographical errors that need to be fixed before I print more. But it works as a proof of concept :) Thanks for the awesome idea!</p>
<p>This is a cool idea! I don't have the business cards yet, but I've written a chip to open a link to a published BI report that serves as an interactive resume. Definitely gotten props from the people I've shown it to so far. Now I just need to business cards to make it complete :)</p>
<p>This is cool and I thought hmm maybe making dog tags but then a QR code works just as good and is free to print. Is there an advantage to this over QR codes?</p>
the advantage is that the only thing u need to do in nfc is simply touch your phone its fast and easy with no apps to download comparing to QR
Very useful thing. Thanks to share!
<p>This is a really cool idea. Nicely done!</p>
