    // Note: Requires Chilkat v9.5.0.77 or greater.

    cert := chilkat.NewCert()

    // Load the certificate on the smartcard currently in the reader (or on the USB token).
    // Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
    // See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
    success := cert.LoadFromSmartcard("")
    if success != true {
        fmt.Println(cert.LastErrorText())
        cert.DisposeCert()

    cert.SetSmartCardPin("000000")

    // Check to see if the SmartCardPin property contains the valid PIN for the smartcard.

    if pinValid == 1 {

    }
    else {
