**WARNING: FOILLOWING THESE INSTRUCTIONS WILL DESTROY THE MASTER KEY ON YOUR CARD. ONLY PROCEED IF NO FUNDS ARE ASSOCIATED WITH THESE ACCOUNTS**
You can use status' [keycard-cli](https://github.com/status-im/keycard-cli) and you should get version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.1.1/keycard_v2.1.1.cap)
You can use status' [keycard-cli](https://github.com/status-im/keycard-cli) and you should get _at least_ version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.2.1/keycard_v2.2.1.cap)
You also need to make sure that the PCSC daemon is running on your system.
Then, you can install the application to the card by typing:
```
keycard install -a keycard_v2.1.cap
keycard install -a keycard_v2.2.1.cap && keycard init
```
Then you can initialize the application by typing:
At the end of this process, you will be provided with a PIN, a PUK and a pairing password. Write them down, you'll need them shortly.
Start `geth` with the `console` command. You will notice the following warning:
```
keycard init
WARN [04-09|16:58:38.898] Failed to open wallet url=pcsc://044def09 err="smartcard: pairing password needed"
```
Then the card needs to be paired:
Write down the URL (`pcsc://044def09` in this example). Then ask `geth` to open the wallet:
```
keycard pair
> personal.openWallet("pcsc://044def09")
Please enter the pairing password:
```
Finally, you need to have the card generate a new master key:
Enter the pairing password that you have received during card initialization. Same with the PIN that you will subsequently be
asked for.
If everything goes well, you should see your new account when typing `personal` on the console:
```
keycard shell <<END
keycard-select
keycard-set-pairing PAIRING_KEY PAIRING_INDEX
keycard-open-secure-channel
keycard-verify-pin CARD_PIN
keycard-generate-key
END

WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=pcsc://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
{
listAccounts: [],
listWallets: [{
status: "Empty, waiting for initialization",
url: "pcsc://044def09"
}],
...
}
```
So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
```
> personal.initializeWallet("pcsc://044def09")
"tilt ... impact"
```
You should get a list of words, this is your seed so write them down. Your wallet should now be initialized:
```
> personal.listWallets
[{
accounts: [{
address: "0x678b7cd55c61917defb23546a41803c5bfefbc7a",
url: "pcsc://044d/m/44'/60'/0'/0/0"
}],
status: "Online",
url: "pcsc://044def09"
}]
```
You're all set!
## Usage
