One of the most popular applications of NFC technology is creating a digital business card that can be shared instantly through an NFC tag, NFC card or NFC-enabled device.
What is it?
A digital business card allows you to share your professional information in a smarter and more interactive way than a traditional paper card. Instead of manually typing a phone number or email address, the user simply taps the NFC card with a smartphone and opens a digital profile.
Traditionally, digital contacts are stored using the vCard standard or .vcf file. This format allows contact details to be exported and imported between different devices and operating systems.
When programming an NFC tag, an NDEF record is typically used. This universal format allows tags programmed with one device to be read correctly by many different devices. Among the available NDEF record types are URLs and vCards.
NFC marketing became much more widespread with the introduction of the iPhone XR. Starting from this model, Apple introduced Background Tag Reading, making the user experience similar to Android. When an NFC tag contains a web link, compatible smartphones automatically open the programmed URL.
However, Background Tag Reading does not currently support all NDEF record types. In particular, the vCard format is not supported directly.
What can you do?
A common workaround is to program the NFC chip with two NDEF records: the first containing the vCard and the second containing a URL.
Android smartphones usually read the first NDEF record they find, opening the contact directly in the address book application.
iPhones, on the other hand, can open the second record containing the web link. The URL should point to a publicly accessible .vcf file, allowing Safari to download and import the contact from the internet.
A smarter alternative: TagLink Business Profile
Today, the most flexible solution is not to store a static vCard directly inside the NFC chip, but to connect the NFC card to a dynamic online profile.
With TagLink Business Profile, you can create a professional digital business card that can include contact details, company information, social media links, reviews, videos and other useful links.
This makes the NFC business card more complete, easier to update and more engaging for the person who receives it. Instead of sharing only a basic contact file, you can offer a branded digital experience that helps you make a stronger first impression.
Why choose a dynamic Business Profile?
A dynamic Business Profile allows you to update your information at any time without reprogramming the NFC chip. This is especially useful if your phone number, role, company details, social links or online content change over time.
It is also a practical solution for companies and teams that want to create professional NFC business cards while keeping control over the information shared by their employees or collaborators.
Useful resources
If you still want to create a .vcf file, you can export it from your address book or use free tools such as vCard Maker.
Once created, upload the file to your own web server or to a cloud storage service such as Google Drive or Dropbox, making sure the file is publicly accessible.
To program the NFC chip, we recommend using a free application such as NFC TagWriter by NXP, available for both Android and iOS.
Pay attention to the chip memory
A complete vCard containing name, surname, company, email address and phone number requires a considerable amount of memory. For this reason, we recommend choosing an NTAG216 chip, which offers enough capacity for a complete contact card.
If you prefer a more flexible and professional solution, you can use an NFC card programmed with a dynamic URL and connect it to a TagLink Business Profile.
