Description

Loss prevention system using master tag and sub tag

The present invention relates to a loss prevention system using a master tag and a sub tag, and more particularly, it can determine whether an item is lost through wireless communication between a sub tag mounted on an item, a master tag, and an application mounted on a mobile phone. It is related to a loss prevention system using master tags and sub tags that can be used.

Among the items, one person carries about two to four personal items, usually wallets, keys, cell phones, notebooks, or diaries. It requires considerable effort.

In addition, in recent years, the penetration rate of portable devices such as electronic dictionaries is rapidly growing through miniaturization of electronic devices and rapid development of communication technology, and the portable devices are becoming very easy to carry due to the trend of miniaturization and weight reduction.

However, this trend improves the user's convenience in using the mobile device, and at the same time, the user does not recognize the mobile device even if it is separated from the user's bag or pocket, and there is a risk of loss. there is a trend to

In the conventional anti-lost system, a transmitter is installed in a mobile device or wallet, and the receiver is mounted on the user's body, and when the transmitter is separated by a predetermined distance, a predetermined warning sound is generated in the receiver.

However, since such a conventional loss prevention system transmits and receives one-to-one transmission and reception, in order to prevent the loss of a plurality of items at the same time, a plurality of transmitters are mounted on the items, which is expensive, and it is difficult to possess a plurality of receivers. There is a problem in that user discomfort is caused.
