To overcome this In , Schuss and Rahkonen described the use of mobile problem at minimized costs, we employ a dedicated stationary phones as microcontrollers for control applications such as smart phone that is supported with the NFC technology to maximum power point tracking which is usually carried out by provide access management for the keys accurately, safely and microcontroller. They presented a mobile application using a efficiently. In addition, we seek an interactive web simple interface to increase the energy gained from PV cells application, which features the tracking of keys with a web without the need for an additional microcontroller. browser. In the rest of this section, we review the important existing NFC is a short-range wireless communication technology that systems used to lock/unlock the doors. The first system of this enables two electronic devices to establish. The opportunities the key card door lock system, which a security system that provided by combining the technology of NFC with the allows users to access doors with an electronic keycard instead capabilities of modern smartphones are summarized in. of a traditional key. The main advantages are having high NFC tag is placed on each key and when the tapping with the reliability, good security, and high speed dependent on RFID smart phone to know the key which was taken and the person (Radio-frequency Identification) protocol. The main who took this key and are recorded the borrow process in the disadvantage of this system is that not work when the key card records for reference when needed. is lost and in general it has high costs. Fingerprint door lock systems are getting more and more popular. Advantages The system is divided into subtasks, e.g. identifying the such systems are having a high reliability for authorized employee, identifying the keys’, storing the information, people but a fingerprint scan door lock needs electricity to run, connect the mobile application to website and make a mobile and any power failure could hinder it totally useless. application as a microcontroller to locks/unlocks the door Another type of door lock systems is using a smartphone automatically. dependent on communication technologies e.g. Bluetooth and The actors who are using this system and the functions of the Wi-Fi. The main advantages of this system are having high system are shown in Figure 2. speed compared with other systems and reliability for opening door only for authorized people. However, the main disadvantages of the system are poor radiality and being not secure when the mobile is lost. The final similar system is a code based keyless door lock system, which got popularity in the last few years. The main advantage is no need to carry the key all the time. Forgetting the passcode is main disadvantage. The previous systems are needed at each door to distinguish employees, but our system needs just one set to incorporate all the keys of the organization, which minimizes the costs. III. METHODOLOGY This system allows employees to borrow the keys of laboratories and rooms using a mobile application based on NFC technology with storing all information about this process automatically in an electronic record eliminating the need for paper records. In an addition, the system identifies employees before any borrowing process who are eligible to borrow keys from the keys-cabinet. The mobile application is linked to the cloud to store keys track information for future use. The flowchart is shown in Figure 1: Figure 2: Flowchart scenario for the application A. Mobile application as a microcontroller A mobile application is a type of application software designed to run on a mobile device, such as a smartphone or a tablet. Mobile applications frequently serve to provide users with similar services to those accessed on PCs. As mobile use continues to grow worldwide, the “app vs. web” question will remain a very real consideration for organizations seeking to establish a mobile presence. In this project, we used the application to control the opening and closing of the door locker, which contains the keys of the various laboratories the smart phone is used as a microcontroller and is interfaced through the headphone jack without need for another microcontroller. B. NFC based identification of keys and an employees Each employee has a unique NFC identification tag and each key has as well has a unique NFC identification tag accessed by scanning the tag and storing the information in a mobile app. If the employee forgets an NFC tag or loses it, the Figure 1: Flowchart scenario for the application application allows another way for the employee who has the authority to borrow the key through the user name and password, but it is less secure than the first method. When the employee makes a mistake and takes the wrong key, he can interfaces of mobile designed by using wireframe to allow return it using the same mechanism. design easy by Android studio e.g. shown as in Figure 5. C. Interent of things By developing a mobile application connected to the internet via a website, we can track employees’ record and keys at any time and place thus it is an internet of things (IoT) system. The aim is to store the records at the cloud server for the following reasons: Avoid losses of data. Keep ubiquitous access to record files. Get unlimited storage. Allow sharing of record file with concerned staff. A sequence diagram borrow process is shown in Figure 3. Figure 3: Sequence diagram for borrow process The return process is the same as borrow process. Clearly, the admin can add, update and delete any information about employees and keys as shown in Figure 4. Figure 5: User interface wireframe This system allows employees to borrow and return keys. The implementation details are described in the next section. V. IMPLEMENTION AND RESULT When an employee at an institution needs a key of a room to give a lecture, the application should be previously opened and he takes the appropriate key that contains the NFC tag and the system records his attendance through the borrow interface. When the key is returned through the return interface, the systems knows the employee who took and the time of return and records the return data. Figure 4: Sequence diagram for admin process A.

It includes requirements gathering, planning, management system (RDBMS). Like other RDBMSs, data is analysis & design, implementation and deployment. The accessed in a SQLite database by using Structured Query Language (SQL). The main package is 'android.database.sqlite' that contains the classes to manage your own databases, In order to create a database one just need to call this method openOrCreateDatabase with his database name and mode as a parameter. It returns an instance of SQLite database which one must receive in his own object. B. Connection between system elements To link the project elements together communication techniques is needed. Therefore, the employee should have an NFC identification tag to allow him to borrow and he should have eligible to access the key locker. On the other hand, the application must be connected to the Internet so that the process of lending and recording the necessary information in the electronic records available on the website is done successfully. The structure of the system and elements how implantation as shown in the Figure 6. Figure 8: Main UIs of the mobile application D. Hardware components We lock/unlock the door of keys board after identifying the authorized employees by NFC tags. A smart phone acts as a microcontroller interfaced via a headphone jack using a simple DTMF (Dual Tone Multi Frequency) circuit as shown in Figure 9. Figure 6: Structure of the system and its elements C. Graphical user interface (GUI) Figure 9: DTMF decoder circuit combined with H-bridge circuit This circuit identifies the dial tone from the telephone line or mobile device and decodes the key pressed on the remote telephone. For the detection of DTMF signal, we use the MT8870DE, which is a touch-tone decoder IC. It decodes the input DTMF to 5 digital outputs. The M-8870 DTMF decoder IC uses a digital counting technique to determine the frequencies of the limited tones and to verify that they correspond to standard DTMF frequencies. We combine this circuit with electrical center lock motor to open and close the door automatically using headphone jack in the mobile. The Figure 7: Main UIs results of the mobile application center lock motor is mounted on the door of the key-cabinet is shown in Figure 10.  consumes time and efforts. To the best of our knowledge, this is the first proposal for using NFC tags for key management application. Certainly, much improvement can be done after getting feedback from the users.
