# How to Make an NFC Business Card In today's digital-first world, the traditional paper business card feels increasingly outdated. I remember attending a major tech conference last year and coming home with a stack of cards, most of which I eventually misplaced or recycled. The experience was frustrating and inefficient. This personal frustration led me to explore a smarter solution: **how to make an NFC business card**. An NFC business card is a physical card embedded with a Near Field Communication chip that, when tapped against a compatible smartphone, can instantly share your digital contact details, portfolio link, or even a calendar scheduling link. It merges the tangible professionalism of a physical card with the power and dynamism of digital technology. ## The Core Components and Technology Behind NFC Business Cards Creating an NFC business card involves understanding its technical foundation. My own journey into this began not as a marketer, but as a tech enthusiast with a knack for understanding hardware-software integration. This personal skill allowed me to deconstruct the process effectively for my own startup. ### Understanding NFC Technology and Chips The heart of an NFC business card is the NFC inlay or tag. This is a thin, flexible circuit containing a microchip and an antenna. The chip is programmed with a URL (your digital business card) or a specific data payload. **Technical Indicators and Detailed Parameters of a Typical NFC Chip (for Business Cards):** * **Chip Model/Code:** Common chips include **NTAG213, NTAG215, or NTAG216** from NXP Semiconductors. The ST25TA series from STMicroelectronics is also popular. * **Memory Capacity:** * **NTAG213:** 144 bytes user memory, sufficient for a URL and basic text. * **NTAG215:** 504 bytes user memory, allows for more data or a longer URL. * **NTAG216:** 888 bytes user memory, offers the most flexibility for data storage. * **Communication Protocol:** ISO/IEC 14443 Type A, operating at 13.56 MHz. * **Read/Write Distance:** Typically 1-4 cm, depending on antenna design and phone model. * **Detailed Dimensions (Chip Inlay):** A standard business card inlay might measure **85.6mm x 54mm x 0.76mm** (ID-
