Single identity in check-in using NFC in airport

One of the concerns related to airline services is the long time for transactions such as, the check-in process, due to the time required for each transaction and the number of transactions for each passenger. Also, the conventional check-in process also requires paper which its use is rapidly rising due to the increasing number of passengers. In this study, an NFC based system was applied to accelerate transactions and to reduce the use of paper. This study was theoretical research focusing on the implementation of mobile transaction in airports and NFC-based single identity. Little research discussing the check-in process in airports has focused on the use of SI. Many studies on the use of NFC are mainly about tracking baggage and baggage claim, yet they do not include the check-in process. This study found that the implementation of SI could accommodate the check-in process in airports and decrease the redudancy of passenger data. The result revealed that the application could uitilise SI to retrieve the citizenship data and reservation data, and check-in data. It could be concluded that the use of NFC in aiports could ease data management, shorten the check-in process, and validate citizenship data using with reservation data
