+# 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

+//
+// This implementation of smartcard wallets have a different interaction process
+// to other types of hardware wallet. The process works like this:
+//
+// 1. (First use with a given client) Establish a pairing between hardware
+// wallet and client. This requires a secret value called a 'pairing password'.
+// You can pair with an unpaired wallet with `personal.openWallet(URI, pairing password)`.
+// 2. (First use only) Initialize the wallet, which generates a keypair, stores
+// it on the wallet, and returns it so the user can back it up. You can
+// initialize a wallet with `personal.initializeWallet(URI)`.
+// 3. Connect to the wallet using the pairing information established in step 1.
+// You can connect to a paired wallet with `personal.openWallet(URI, PIN)`.
+// 4. Interact with the wallet as normal.
