Linux, macOS, Windows: [![](https://github.com/bluetech/pcsc-rust/workflows/CI/badge.svg?branch=master)](https://github.com/bluetech/pcsc-rust/actions/)

Rust bindings to the PC/SC API for smart card communication.

- Nice, safe API.
- Tested on Linux, Windows, macOS.
- Mostly zero overhead.

See the [Documentation](https://docs.rs/pcsc) for more details.

See the `pcsc/examples` directory for some common tasks.

## Contents

The [`pcsc-sys`](https://docs.rs/pcsc-sys) crate contains direct,
low-level bindings to the C API.

The [`pcsc`](https://docs.rs/pcsc) crate contains high-level Rust
wrappers.

## Usage

In your `Cargo.toml`:

```toml
[dependencies]
pcsc = "2"
```

## Example

Connect to the card in the first available reader, send the card an
APDU command, print the APDU response.

```rust
use pcsc::*;

fn main() {
// Establish a PC/SC context.
let ctx = match Context::establish(Scope::User) {
Ok(ctx) => ctx,
Err(err) => {
eprintln!("Failed to establish context: {}", err);
std::process::exit(1);
}
};

// List available readers.
let mut readers_buf = [0; 2048];
let mut readers = match ctx.list_readers(&mut readers_buf) {
Ok(readers) => readers,
Err(err) => {
eprintln!("Failed to list readers: {}", err);
std::process::exit(1);
}
};

// Use the first reader.
let reader = match readers.next() {
Some(reader) => reader,
None => {
println!("No readers are connected.");
return;
}
};
println!("Using reader: {:?}", reader);

// Connect to the card.
let card = match ctx.connect(reader, ShareMode::Shared, Protocols::ANY) {
Ok(card) => card,
Err(Error::NoSmartcard) => {
println!("A smartcard is not present in the reader.");
return;
}
Err(err) => {
eprintln!("Failed to connect to card: {}", err);
std::process::exit(1);
}
};

// Send an APDU command.
let apdu = b"\x00\xa4\x04\x00\x0A\xA0\x00\x00\x00\x62\x03\x01\x0C\x06\x01";
println!("Sending APDU: {:?}", apdu);
let mut rapdu_buf = [0; MAX_BUFFER_SIZE];
let rapdu = match card.transmit(apdu, &mut rapdu_buf) {
Ok(rapdu) => rapdu,
Err(err) => {
eprintln!("Failed to transmit APDU command to card: {}", err);
std::process::exit(1);
}
};
println!("APDU response: {:?}", rapdu);
}
```

Example output:

```
$ ./target/debug/examples/readme
Using reader: "SCM Microsystems Inc. SCR 355 [CCID Interface] 00 00"
Sending APDU: [0, 164, 4, 0, 10, 160, 0, 0, 0, 98, 3, 1, 12, 6, 1]
APDU response: [106, 130]
```
