  1. Introduction

In a world driven by technology and connectivity, business cards have evolved from simple paper-based designs to high-tech tools that can bridge the gap between offline and online networking. Near Field Communication (NFC) business cards are at the forefront of this evolution, offering dynamic ways to share contact information, websites, or social media profiles. But can they go one step further and be programmed to call a phone number directly? Let’s explore this possibility in detail.

  1. What Are NFC Business Cards?

NFC business cards](https://evrycard.co.uk/nfc-business-cards/) are a modern upgrade to traditional business cards, equipped with embedded NFC chips. These chips allow users to share digital information instantly by tapping the card on an NFC-enabled smartphone or device. Unlike QR codes, NFC does not require scanning a visible code, making it a seamless experience.

Key Features of NFC Business Cards:

  • Instant sharing of contact details.
  • Redirection to websites, portfolios, or social media pages.
  • Customizable functionality, including calls or emails.
  1. How Do NFC Business Cards Work?

NFC technology relies on wireless communication between two devices—an NFC tag (the chip in the card) and an NFC reader (usually a smartphone). When the devices come into close proximity, data stored on the NFC chip is transmitted to the reader.

Basic Components of NFC Cards:

  • NFC Chip: Stores data like contact details or commands.
  • Antenna: Allows the card to communicate with NFC-enabled devices.
  • Encoding: Determines what action the NFC chip will trigger.
  1. Programming NFC Business Cards: The Basics

To program an NFC business card, you’ll need an NFC-compatible device and an app that allows encoding, such as NFC Tools or TagWriter. These apps enable you to write specific data to the NFC chip, such as:

  • URLs
  • Text messages
  • Contact details (vCard)
  • Commands like calling a phone number

Programming is user-friendly and requires no advanced technical skills.

  1. Can NFC Business Cards Call a Phone Number Directly?

Understanding Direct Call Programming

Yes, NFC business cards can be programmed to call a phone number directly. When tapped on an NFC-enabled smartphone, the card can initiate a call by executing a pre-programmed command. This functionality is achieved using the "tel:" URI scheme.

How It Works:

  • The NFC chip stores a command like tel:+1234567890.
  • When a smartphone reads the chip, it interprets this command and opens the dialer app with the specified number pre-filled.
  • The user only needs to press the call button to connect.

While direct calling is possible, it’s essential to understand that security and user permission are key considerations. Most smartphones require user confirmation before placing a call.

  1. Step-by-Step Guide to Programming NFC Cards for Direct Calls

Here’s how you can program your NFC business card to initiate a call:

Materials Needed:

  • NFC business card with writable NFC chips.
  • NFC-enabled smartphone.
  • A programming app (e.g., NFC Tools, TagWriter).

Steps:

  1. Download and Install an NFC App: Choose a reliable app like NFC Tools (available for iOS and Android).

  2. Open the App and Select "Write": Navigate to the write function within the app.

  3. Enter the Call Command: Input the command in the format tel:+[CountryCode][PhoneNumber]. For example, tel:+1234567890.

  4. Place the NFC Card Near Your Phone: Hold the card close to your phone’s NFC reader.

  5. Write the Command to the Card: Confirm the command and wait for the app to write it to the NFC chip.

  6. Test the Functionality: Tap the card on an NFC-enabled smartphone to ensure it opens the dialer with the correct number.
