+# Using the smartcard wallet
+
+## Requirements
+
+  * A USB smartcard reader
+  * A keycard that supports the status app
+  * PCSCD version 4.3 running on your system **Only version 4.3 is currently supported**
+
+## Preparing the smartcard
+
+  **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 _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_v2.2.1.cap && keycard init
+  ```
+
+  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:
+
+  ```
+  WARN [04-09|16:58:38.898] Failed to open wallet                    url=keycard://044def09                          err="smartcard: pairing password needed"
+  ```
+
+  Write down the URL (`keycard://044def09` in this example). Then ask `geth` to open the wallet:
+
+  ```
+  > personal.openWallet("keycard://044def09")
+  Please enter the pairing password:
+  ```
+
+  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:
+
+  ```
+  > personal
+  WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=keycard://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
+  {
+    listAccounts: [],
+    listWallets: [{
+        status: "Empty, waiting for initialization",
+        url: "keycard://044def09"
+    }],
+    ...
+  }
+  ```
+
+  So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
+
+  ```
+  > personal.initializeWallet("keycard://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: "keycard://044d/m/44'/60'/0'/0/0"
+    }],
+    status: "Online",
+    url: "keycard://044def09"
+  }]
+  ```
+
+  You're all set!
+
+## Usage
+
+  1. Start `geth` with the `console` command
+  2. Check the card's URL by checking `personal.listWallets`:
+
+```
+  listWallets: [{
+      status: "Online, can derive public keys",
+      url: "keycard://a4d73015"
+  }]
+```
+
+  3. Open the wallet, you will be prompted for your pairing password, then PIN:
+
+```
+personal.openWallet("keycard://a4d73015")
+```
+
+  4. Check that creation was successful by typing e.g. `personal`. Then use it like a regular wallet.
+
+## Known issues
+
+  * Starting geth with a valid card seems to make firefox crash.
+  * PCSC version 4.4 should work, but is currently untested
