Getting started
from the ZIP to a card that opens your app.
The shortest path through the kit. Each step links to the page with the details. You can do steps 1 and 2 without any card or reader.
01Quick start, step by step
- Unzip the kit. You get four folders under
apps/:nfc_crypto,cryptocard_wallet,nfc_recoveryandcard_studio. See What is in the ZIP. - Try Card Studio without hardware. On a Mac:
cd apps/card_studio && ./run.sh --simulate. On Windows: double-clickrun.bat, then turn on Settings → Simulated reader. Click Load sample data on the Dashboard. See Card Studio. - Run NFC Crypto on a phone.
cd apps/nfc_crypto, copy.env.exampleto.env, thenflutter pub getandflutter run --dart-define-from-file=.env. NFC needs a real phone; a simulator shows the screens only. See Installation. - Pair a card. In the app, open the Card tab → Pair a new card (or the Pair card quick action once you have cards), and hold an NTAG215 or NTAG216 card to the phone. The first card becomes the Owner card. See Card roles and limits.
- Put your brand on it. Change the app name, colours, card host and bundle ID. See White label.
- Host your card domain. Put the Apple and Android app-link files on your own domain, so a card tap opens your app on iPhone. See Card host setup.
- Build for the stores. Sign with your own Apple team and Android key. See Build and release.
02Which app first
| If you want to… | Start with |
|---|---|
| Sell a phone wallet that a card confirms | NFC Crypto (apps/nfc_crypto) |
| Sell a card that holds the wallet itself | CryptoCard Wallet (apps/cryptocard_wallet). It starts on test networks. |
| Give customers a way to read their backup without the wallet | NFC Recovery (apps/nfc_recovery) |
| Prepare, track and ship cards as an operator | Card Studio (apps/card_studio) |
All four apps read and write the same card format, so you can start with one and add the others later. See Card format.
03Before you sell cards
- Read Security model and limits. NTAG215 and NTAG216 cards can be copied by whoever holds them.
- Read what spending limits are, and are not. They are rules of the app on one phone, not rules on the blockchain.
- Check what the law asks of you where you sell. A wallet or card product can be regulated. That is your responsibility, not the kit's.
