Within the website or mobile app, one can create a message and attach a target address to which it is sent to. If another user is near the address of the message, while he opens our mobile app to check local news, he can see the message. Also, if a user has followed the address, he is able to see the message in his information stream even if he is not nearby. Advertisers can use our products to send refined information to a target place. When a user checks what is going on in his local community, he can see all the information sent here. It is as if an information board is set up to a specific location, with which one can reach another person or organization globally and attract their attention. This has an advantage over the other internet services as most of current available internet products are just waiting for visitors, while our products reach people proactively.
