nfc-pcsc | Easy reading and writing NFC tags and cards in Node.js | Runtime Evironment library

You will need a version of the Electron application built for your GNU/Linux distribution. But if you cannot get that, something built for an older version of another distribution (such as Debian jessie or Red Hat Enterprise Linux 7) might help. Unfortunately, you do not say which distribution and version you are using, so it is difficult to make proper recommendations.

Another alternative is building Electron yourself from source, on your system, but given the size of Electron's dependencies, that can be quite an effort.

You need to include the electron-rebuild package which rebuilds native Node.js modules against the version of Node.js that your Electron project is using. This allows you to use native Node.js modules in Electron apps without your system version of Node.js matching exactly.

You can install this package using the below command,

It seems that you first authenticate to all sectors and then try to read some data from these sectors. However, this is not how MIFARE Classic authentication works. Instead, will need to authenticate to a sector (e.g. use reader.authenticate(4, keyTypeB, key_b) to authenticate with key B for the whole sector 1). You can then read data from any block of that sector (where key B is granted read access). After you finished reading from that sector, you can authenticate to the next sector (e.g. reader.authenticate(8, keyTypeB, key_b) to authenticate with key B for the whole sector 2). You can then read data from any block of that sector (where key B is granted read access).

Also note that the default configuration for "empty" MIFARE Classic cards is Key A = FFFFFFFFFFFF, Key B = not used, read/write with Key A only. Since, the areas containing the keys are not readable (unless a key is not used), reading "000000000000" from those memory regions usually just means that no data could be read, the actual key could still be some other value. Thus, if you are sure that the cards a empty and have default permissions set, I would suggest to try to authenticate using "FFFFFFFFFFFF" as key A:

I suggest you to use the express API command with npm CLI : npm install --save express at your root project folder in your terminal Then, you will be able to create a route in Get, Post, Put or Delete. Next, In your client side you will be able to call this route by a get, post or whatever with a promise, ajax request whatever you want :) Just understand that in order to receive or send data to your server, you need an url and with Express, you can create your own url.

Don't hesitate to have a look on this API, and i'm pretty sure you will find the answer to your question on your own :)
