Interface Transaction

Represents a temporary CardMode.EXCLUSIVE connection session, which can be started from a CardMode.SHARED connection via Card.transaction().

Example:

import * as pcsc from "pcsc-mini";

async function longRunningProcess(card: pcsc.Card) {
  const txn = card.transaction();

  try {
    const r1 = await card.transmit(Uint8Array.of(0xca, 0xfe, 0xf0, 0x0d));
    const r2 = await card.transmit(Uint8Array.of(0xfa, 0xde, 0xfa, 0xce));

    return processResults(r1, r2);
  } catch (err) {
    console.error("Something went wrong:", err);
  } finally {
    txn.end(pcsc.CardDisposition.LEAVE);
  }
}
