This is a relict and Example Implementation of a NFC Scanner connected via a Websockets API Using the Feathers Framework
how to create a NodeJS Application that uses a ACR122 USB reader but it should work with all PC/SC compliant devices
npm i .....Implement Reader hardware via Posix Methods and Event Emitters so linking fileDescriptors and implement the main Reader Protocol.
This example used feathers to abstrack IPC and RPC Handling via a external exposed API. Today we would prefer to use raw net sockets and JSON as RPC. To send Binary Data eg none C UTF-8 including 0x00 bytes as array of integers inside the json. the JSON Parse Method will turn it back into byte buffer view without overhead.
A feathers js Service using pcsc bindings.
Built-in support for auto-reading card UIDs and reading tags emulated with Android HCE.
NOTE: Reading tag UID and methods for writing and reading tag content depend on NFC reader commands support. It is tested to work with ACR122 USB reader but it should work with all PC/SC compliant devices.
When detecting tags does not work see Alternative usage.
This library uses pscslite native bindings pokusew/node-pcsclite under the hood. pokusew/nfc-pcsc
