Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var scmd = new CkScMinidriver();

// Reader names (smart card readers or USB tokens) can be discovered
// via List Readers or Find Smart Cards
var readerName = "Alcor Micro USB Smart Card Reader 0";
success = scmd.AcquireContext(readerName);
if (success == false) {
    console.log(scmd.LastErrorText);
    return;
}

// If we are successful, the name of the currently inserted smart card is available:
var cardName = scmd.CardName;
console.log("Card name: " + cardName);

// Also, the ATR of the inserted card is available (you will likely not need the ATR).
console.log("ATR: " + scmd.Atr);

// Also, the maximum number of key containers is readily available:
console.log("Max number of key containers = " + scmd.MaxContainers);

// Delete the context when finished with the card.
success = scmd.DeleteContext();
if (success == false) {
    console.log(scmd.LastErrorText);
}

// Sample output:

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