ScMinidriver - Acquire Context with Smart Card or USB Token

See more ScMinidriver Examples

Initializes communication with the card inserted in the given reader (or a USB token). Reader names can be discovered via the SCard.ListReaders or SCard.FindSmartcards methods. If successful, the Atr and CardName properties will be set. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let scmd = chilkat::ScMinidriver::new();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
let reader_name = "Alcor Micro USB Smart Card Reader 0".to_string();
if scmd.acquire_context(&reader_name).is_err() {
    println!("{}", scmd.last_error_text());
    return;
}

// If we are successful, the name of the currently inserted smart card is available:
let card_name = scmd.card_name();
println!("Card name: {}", card_name);

// Also, the ATR of the inserted card is available (you will likely not need the ATR).
println!("ATR: {}", scmd.atr());

// Also, the maximum number of key containers is readily available:
println!("Max number of key containers = {}", scmd.max_containers());

// Delete the context when finished with the card.
if scmd.delete_context().is_err() {
    println!("{}", scmd.last_error_text());
}

// Sample output:

// Card name: IDPrime MD T=0
// ATR: 3B7F96000080318065B0855956FB120FFE829000
// Max number of key containers = 20
