A method for communication, comprising:

• writing first information in a specific memory space of a storage in a first device in response to a trigger operation by a user;
• transmitting, by a first wireless communication, the first information to a second device when the second device is within a first distance to the first device for a first time;
• writing second information in the specific memory space of the storage;
• and
• transmitting, by the first wireless communication, the second information to one or more other devices when the one or more other devices are within the first distance to the first device at following times.

A communication system comprising a first device and a second device,

• the first device comprising:
• a storage configured to be re-writable;
• a first communication circuit configured to perform first wireless communication with other devices and provide information stored at a specific memory space of the storage to the other devices when the other devices are within a first distance to the first device;
• and
• a controller configured to
• write first information in the specific memory space of the storage in response to a trigger operation by a user, the first information being transmitted to the second device by the first communication circuit when the second device is within the first distance to the first device for a first time;
• and
• write second information in the specific memory space of the storage, the second information being transmitted by the first communication circuit to one or more other devices when the one or more other devices are within the first distance to the first device at following times.
