# Steps for making a bolt card with the Android app
|
|
|
|
## Introduction
|
|
|
|
Here we describe how to create your own bolt cards with the Bolt Card service and the Bolt Card Android app.
|
|
|
|
## Resources
|
|
|
|
- some `NXP DNA 424 NTAG` cards
|
|
- an Android device with NFC
|
|
- a Bolt Card service
|
|
- [the Bolt Card app](https://github.com/boltcard/bolt-nfc-android-app)
|
|
- [the Bolt Card app usage document](https://github.com/boltcard/bolt-nfc-android-app#usage)
|
|
|
|
## Steps
|
|
|
|
### Install the app
|
|
|
|
- install the app from
|
|
- source
|
|
- apk
|
|
- Google Play Store [Boltcard NFC Card Creator](https://play.google.com/store/apps/details?id=com.lightningnfcapp)
|
|
|
|
### Write the key values to the card
|
|
on the bolt card server
|
|
- ensure the environment variables for the database connection are set up (see `boltcard.service`)
|
|
this can be achieved by writing these lines to the end of the `~/.bashrc` file
|
|
```
|
|
echo "writing database_login to env vars"
|
|
|
|
export DB_HOST=localhost
|
|
export DB_PORT=5432
|
|
export DB_USER=cardapp
|
|
export DB_PASSWORD=database_password
|
|
export DB_NAME=card_db
|
|
|
|
echo "writing host_domain to env vars"
|
|
|
|
export HOST_DOMAIN=card.yourdomain.com
|
|
```
|
|
- enter the `createboltcard` directory
|
|
- `$ go build`
|
|
- run the creation program
|
|
- `./createboltcard -help` to see options
|
|
- `./createboltcard -enable -tx_max=1000 -day_max=10000 -name=card_1` for example
|
|
- this will give you a one-time link in text and QR code form
|
|
|
|
on the app
|
|
- click `scan QR code`
|
|
- scan the QR code
|
|
- the app will prompt you to hold the card for programming
|
|
- the app will test the card and show you the results
|
|
|
|
### Make a payment
|
|
- monitor the bolt card service logs
|
|
- `$ journalctl -u boltcard.service -f`
|
|
- use a PoS setup to read the bolt card, e.g. [Breez wallet](https://breez.technology/)
