# Implementation of Smart NFC Door Access System for Hotel Room
## 4 Findings and Discussion  
Throughout gathering the responses on the questionnaire, a total of 33 responses are recorded. Some additional opinions and requirements are also collected from the respondents. After gathering an adequate number of responses, the analysis will then be accomplished to extract and transform the data from the questionnaire into useful information for further development of the proposed system. The analysis will be elaborated on in the following statements. Convenience sampling will be used in the quantitative study. Responses from random convenience sampling are a non-probability type of sampling utilised frequently in qualitative research in population studies. Convenience sampling for qualitative research is taken from people that are easy to contact or reach. The reason for using random convenience sampling responses is it is useful when used to generate a potential study objective. Besides that, it is popular because it is not costly, not time-consuming, and simplistic. In Figure 7, the data shows that the respondents are mostly from Melaka, Negeri Sembilan, and Johor. Therefore, the research hotel is based in those states in Malaysia. The problems encountered for using the current access system are increasing due to the traditional method and inconvenience. Besides that, the current access system does require high implementation costs. Figure 8 shows the number of respondents has faced the problem in the hotel. 81.8% of the respondents encounter the problem from the current access system. While 18.2% of the respondents do not encounter the problem from the current access system. This can conclude that the current access systems have problems that require enhancing them. Figure 8: The number of respondents who encounter a problem. Figure 7: Location of the respondents. The problems encountered by 81.80% of respondents are the key and the card being lost or damaged, the access system requiring manual and physical interaction, and the access system having low-level security and inconvenience. Hence, the solution is to develop an NFC access system, which allows users to use their smartphones to access the hotel room door. These can reduce the number of keys and cards lost and damaged, the access system is built to be a contactless access system and has a high level of security and convenience. The respondents are excited to have a newly developed NFC access system in the hotel. The newly developed access system with the NFC function will improve the hotel industry business. The respondents agree to have an NFC access system in Figure 9.  
As can be seen, a total of 100% of the respondents supported deploying the NFC access system in the real world. The comments are directly linked to the recommendation to use cell phones rather than the shown access system in Figure 9.  
The impacts of using the NFC access system are NFC access system allows user to access their hotel room door without manual or physical interaction. NFC has a high level of security so that the user may feel more secure using the access system. Lastly, the NFC access system provides a contactless environment in the hotel. As a result, the NFC access system reduces the hotel guests' and staff's concern about the spread of the pandemic and enjoy a new technology environment in the hotel. The respondents agree to use a single device gadget concept of access system in the hotel based on Figure 10.  
There are 32 out of 33 respondents agreed to use the single device gadget idea. The reason is that it is convenient for users as the NFC access system only requires an NFC smartphone to access the hotel room in the hotel. As we know, the smartphone is one of the most important items in our life in this century. Therefore, the users will not lose and damage the traditional access system.
