In this paper, we proposed an electronic attendance-absence recording system using a smartphone that does not require separate BLE(Bluetooth Low Energy) devices and infrastructure by using BLE advertisement technology of smartphone. The existing BLE-based electronic attendance-absence recording system requires a BEL device to be attached to each classroom for services and a separate technology to identify the devices attached to the classroom. Also, due to the interference with each other, sometimes an error occurred in the electronic connection. In this paper, we propose a system to solve the problems about time, place and cost, which is a disadvantage of the conventional Bluetooth beacon system. BLE advertising function of the smartphone that the user is using without BLE device, it is possible to construct infrastructure for electronic attendance-absence recording system. In order to evaluate the effectiveness of the proposed system, we designed the system structure and operation flow and constructed the system using the smart phone in actual used.

Untact order payment has become a new normal since the COVID-19. BLE beacon is a technology that supports low-power wireless communication within 70 meters without Bluetooth pairing and is specialized for indoor positioning. Therefore, it is suitable for building and providing O2O services beyond B2C and B2B services. However, beacons have a lower utilization rate because they have fewer platforms than wifi that support long-distance wireless communication. Therefore, this paper aims to provide more convenient non-face-to-face related services than before by designing and proposing an O2O service platform using BLE beacons. When scanning beacons, not only does it receive advertising data that beacons have, but it also ensures that the actual distance between the user's terminal and beacons is accurately calculated. Through accurate location, the O2O service platform will be able to provide users with store information, such as coupons and discounts, museum exhibits, and traffic information at the right time.

Bluetooth 4.0 is a low energy near communication technology. It is a suitable for Internet of Things(IoT), that is, all devices using small electric power consume are connected because power consumption is more lowing and brodening for application scope against bluetooh 3.0. Therefore in this paper, a present situation of beacon technologies are investigated and a design principle of restaurant advertisement and order system using beacon technology are presented. A beacon which is tranceiver based on bluetooth 4.0 technology and bluetooth 4.0 receiver device design is showed and design method of smart-phone interlocking these devices is presented. Also it shows that this design method is very useful for the Restaurant Advertisement & Order Commercial System production.

Beacons have been noted in the core of the recent things Internet. It is also the technology is spreading most rapidly among the things Internet-related communication technologies. Beacon is a data communications technology that provides information that is customized to know the user's location. Using the BLE technology, to grasp the position of such people and goods. In addition to the non-contact method, since it is possible to communicate within the maximum 70m, it has attracted the interest than the NFC. Beacon, guidance for the current coupon, you can use as an advertising platform, such as the provision of product information, it has also been used in the indoor positioning service. Therefore, in this paper, we introduce about whether Case Study beacon is utilized how in the Internet of Things, were analyzed. Beacon exit the smart phone, the date to be used in conjunction with a wearable device, such as Google glasses and smart watch was not far away. Future it is expected or beacons are used everywhere to be expanded.

Bluetooth 4.0 is the most appropriate technology for Internet of Things, which can be used to enhance and expand the existing areas and areas with a variety of applications. In this paper, an example of the services of the Internet of Things, we developed a tour guide system using the Bluetooth 4.0 and WiFi sensor technology. iBeacon-based push service have been limited to iOS smart phone series, non-iOS family and lower version of iOS 6 smart phones can not receive push-based services. This paper proposed in iBeacon and WiFi sensor is more than tourists, while maintaining the existing system (non-iOS smartphone users) can provide the service to you. Service tourist information as well as that can provide the advertising associated with the service. With 10 kinds of smart phones used in Korea was the experiment on the MAC information collected. This experiment is to track the behaviour of tourists in history can provide customized services can be based. Tourist destinations as well as amusement parks, resorts, etc. If you want to apply this system in a crowded place for user behavior information-gathering feature views over the a prevention of a missing child features such as notifications, risk, prevention is possible for a variety of applications.
