wait method
Sends a wait command to the device. This takes 1 second and once complete it will reduce the authDelay value by one (if > 0). Once an incorrect CVC or Spend Code is entered 3 times you must send 15 wait commands before you can try any secure function again
Implementation
Future<WaitResponse> wait(Transport transport) => Implementation.instance
.cktapcardWait(transport, handle, type)
.then((value) {
authDelay = value.success ? value.authDelay : authDelay;
return value;
});
