+<h1>Bolt cards (NXP NTAG) Extension</h1>

+This extension allows you to link your Bolt card with a LNbits instance and use it more securely then just with a static LNURLw on it. A technology called [Secure Unique NFC](https://mishka-scan.com/blog/secure-unique-nfc) is utilized in this workflow. 
 
+**In order to use this extension you need to be able setup your card first.** There's a [guide](https://www.whitewolftech.com/articles/payment-card/) to set it up with your computer. Hopefully a mobile app is to come to do this. 
 
-<h2>If your extension has API endpoints, include useful ones here</h2>
+<h2>Setting the outside the extension</h2>
 
-<code>curl -H "Content-type: application/json" -X POST https://YOUR-LNBITS/YOUR-EXTENSION/api/v1/boltcards -d '{"amount":"100","memo":"boltcards"}' -H "X-Api-Key: YOUR_WALLET-ADMIN/INVOICE-KEY"</code>
+The URI should be `lnurlw://YOUR-DOMAIN.COM/boltcards/api/v1/scane/?e=00000000000000000000000000000000&c=0000000000000000`
+
+(At this point the link is common to all cards. So the extension grabs one by one every added card's key and tries to decrypt the e parameter until there's a match.)
+
+Choose and note your Meta key and File key. 
+
+<h2>Adding the into the extension</h2>
+
+Create a withdraw link within the LNURLw extension before adding a card. Enable the `Use unique withdraw QR codes to reduce 'assmilking'` option. 
+
+The card UID can be retrieve with `NFC TagInfo` mobile app or from `NXP TagXplorer` log. Use the keys you've set before. You can leave the counter zero, it gets synchronized with the first use.
