# NFC Card Builder — PCB business card with NFC

A free browser tool that makes an 85 × 55 mm circuit board business card with a built-in NFC tag (NXP NTAG I2C plus NT3H2111, LCSC C2654884) and a tuned round 6-turn antenna. Visitors type a name, monogram, up to three contact lines with icons, a tagline, a back title and a link; the tool fits the text around the antenna, draws a QR code, previews both sides in five solder mask colours with silver (HASL) or gold (ENIG) metal, and downloads vector Gerber files, a drill file, order notes, and BOM and CPL files for JLCPCB assembly. Every download passes a manufacturing check (0.15 mm copper and silkscreen, 0.1 mm mask dams). After the cards arrive, the link can be written to the blank chip from the same page with Web NFC in Chrome on Android, or with the NXP TagWriter app. Everything runs in the browser.

## Questions and answers

### Is the NFC Card Builder free?

Yes. Designing and downloading the files is free and needs no account. You pay the board maker for the boards and the chip assembly.

### Does the card really work with phones?

Yes. It has a real antenna made of copper and an NXP NTAG I2C plus chip soldered on by the maker. Phones with NFC read it when they touch the back of the card. Keep metal away from the card while testing.

### Which phones can write the tag from this page?

Writing from a website needs Chrome on an Android phone with NFC turned on. On an iPhone or any other device, use the free NXP TagWriter app. Every phone with NFC can read the card once the link is on it.

### Can I change the link later?

Yes. The tag stays rewritable, so you can write a new link any time. The QR code is printed, so it keeps the link you chose when ordering.

### What is inside the download?

Copper, solder mask and silkscreen layers for both sides, solder paste for the chip, the board outline, the drill file and order notes. BOM and CPL are separate files because JLCPCB asks for them in their own upload fields.

### Is my information uploaded?

No. Everything you type is turned into board files in your browser. Nothing is sent to this website or anyone else until you upload the files to a board maker yourself.

### Can I design something other than this layout?

The antenna and chip stay where they are, because they are tuned and checked. Your text, icons, monogram, QR code, colours and metal finish are yours to choose. For free-form art, use PCB Art Studio.
