Antitheft Technology for Smart Carts Using Dual Beacons and a Weight Sensor

Recently, various forms of theft and loss prevention technologies have been proposed, including beacons for the prevention of missing children, the theft of strollers, and the loss of passports. However, technologies using only one beacon may send a notification that they have been lost even when they are not outside the range of the beacon signal. In addition, this technology often fails to prevent loss because it only sends an alarm to smart devices after they are a long distance from the owner. Therefore, we propose a technology that uses two beacons to improve antitheft performance. At the same time, we propose an antitheft technology for smart carts using dual beacons and a weight sensor. To verify the performance of the proposed method, we performed a comparative experiment with an existing method using one beacon, and the experimental results showed that the proposed method had 96.5% accuracy. In addition, the antitheft technology using a weight sensor also confirmed that the theft notification was highly accurate. Thus, the proposed technology will be useful for protecting the luggage of those who use airport smart carts and will also be useful for a variety of other purposes, including the prevention of missing children, the theft of strollers, and the loss of passports.
