After the user has returned to you via your `merchant_return_url`, you retrieve the `transaction_id` from the `trxid` query parameter and the `entrance_code` from the `ec` query parameter appended to your `merchant_return_url`.
Use the `entrance_code` to retrieve the QR code ID for the user and send it with the `transaction_id` to retrieve the status.
Personal information will only be returned once by this call. If you need the information a second time, you will have to make a new iDIN request for the consumer.
