В текущей реализации поиск производится только по card_id. Для поиска по другим критериям код требуется дорабатывать.

function rpcf_search_cards($card_id) { //0x1201
	$ret=array();
	if (!$this->connection->urfa_call(0x1201)) {

	$packet->DataSetInt(3); //criteria_id '='
	$packet->DataSetString($card_id); //card_id
	$this->connection->urfa_send_param($packet);
