Last month, after Apple released AirTag, an anti loss device, the issue of anti loss and the popularity of related products were increased. Recently, Alipay has also launched the "owner code" for preventing items from being lost.

It is reported that the owner code is a two-dimensional code with anti loss function. According to different use scenarios, there are currently three forms of luggage tag, key pendant and backpack pendant, which can be obtained free of charge after filling in the receiving address and other information. Its anti loss principle is that if someone else finds the lost item, they can contact the owner by scanning the code. The official said that the recovery rate after testing reached 99%.

At the same time, the owner code adopts the "anonymous contact" based on the virtual number, which has the function of privacy protection to prevent the picker from directly obtaining the owner's contact number and other personal contact information.

Compared with the hardware based AirTag, the main code of PayPal, an anti loss technology using two-dimensional codes, has a stronger universality - just like the number of users who scan the code and take the bus is far more than the number of users who swipe the bus card with mobile NFC, and the cost is lower. At the same time, compared with AirTag, it can only use the anti loss network based on iOS devices, In theory, the owner code can use the human resources of the whole society to help the owner find the lost property.

Of course, AirTag also has its own irreplaceable advantage, that is, the owner can actively find the approximate location of the lost object, and it is very flexible in use, and can be placed in any item, while the owner code can only be used passively to wait for the lost object to be found and expect the finder to actively scan the code to contact.
