How to Make an NFC Business Card on Android

What you need

An Android phone with NFC (Android 8.0 or later).
An NFC card, sticker or key tag. Smaller tags hold less, so keep the card short.
Your details: full name, role, company, phone, email and website.

Step 1: Turn on NFC

Open Settings and search for "NFC". Switch it on. On many Android phones it sits under Connections or Connected devices. The NFC antenna is usually near the middle or top of the back of the phone.

Step 2: Choose Digital business card

Open NFC Ninja, tap Write a Tag and choose Digital business card. Or open the Library and tap Use this idea on Digital Business Card.

Step 3: Add your details and preview

Fill in your full name, role, company, phone, email and website. The business card writer is built into NFC Ninja and works the same way on Android and iPhone. Check the preview, including how much space it needs on the tag.

Step 4: Write the card

Hold the card flat against the back of your phone until the write finishes. If the tag already has something on it, NFC Ninja asks before replacing it.

Step 5: Let it check itself

NFC Ninja reads the tag back and only shows success when the contents match, so you know the card works before you hand it out.

Make it look like a real business card

A plain white card works, but a designed one gets kept. With Pro, the Design Studio has a Business Cards category: pick one of 3 layouts, add your headline, details and link, choose your brand colour and a background, and place your logo. Share the design as a PNG or a one-page PDF to send to your designer or print shop. Pro's Card Studio also saves your cards so you can reuse them, keep one per role or per team member, and write them again whenever you need.

Share it with iPhone users too

Your card is not Android-only. iPhone XS and later can read NFC tags, and the person tapping your card does not need NFC Ninja. Contact fields can show slightly differently from phone to phone, so tap your finished card with an iPhone and an Android phone before you print a batch.

Stop people overwriting it

A card you hand out can be rewritten by anyone with an NFC app. Pro's tag security tools let you add a write password, or permanently lock a finished card. Both need NTAG21x tags. Permanent lock cannot be undone: you confirm you understand that and type LOCK, and NFC Ninja reads the tag again right before locking.

Keep it up to date

Your setup is saved in My Tags. When your number or role changes, edit it and write it again (unless you have locked the card).

Frequently asked
questions

Can I make an NFC business card on Android without buying a card from a supplier?

Yes. Buy blank NFC cards or stickers, then write your own details with NFC Ninja. You choose what goes on the card and can rewrite it when your details change.

Do people need an app to read my NFC business card?

No. Most recent Android phones and iPhone XS or later read NFC tags without an extra app. Their phone shows your contact details. How it offers to save them can differ from phone to phone.

Does an NFC business card work with iPhone?

Yes. iPhones from the XS onward can read it. Contact fields can show differently between phones, so check your card on both before printing a batch.

Can I save more than one business card?

Yes, with NFC Ninja Pro. Card Studio keeps saved, reusable cards, so you can switch between cards or write the same card again later.

How do I stop someone changing my card?

NFC Ninja Pro can add a write password or permanently lock the card. Both need NTAG21x tags, and a permanent lock cannot be undone.
