1. A communication apparatus comprising:
- a first communication unit for communicating with other communication apparatus through electric field coupling or magnetic field coupling;
an approach detection unit for detecting an approach between the other communication apparatus and the first communication unit; and
a selection unit for, when the other communication apparatus and the first communication unit are separated from each other, selecting different data to be transmitted depending on a time for which the other communication apparatus and the first communication unit were in close proximity to each other, when the selection unit determines the time is less than a predetermined time, the selection unit selects first data to be transmitted, and when the selection unit determines the time is greater than the predetermined time, the selection unit selects different second data second data to be transmitted.

8. A communication method comprising the steps of:
-
detecting an approach with other communication apparatus communicating through electric field coupling or magnetic field coupling; detecting a separation from the other communication apparatus; and selecting different data to be transmitted depending on a time for which the other communication apparatus is in close proximity, wherein when the selecting determines the time is less than a predetermined time, the selecting selects first data to be transmitted, and when the time is greater than the predetermined time, the selecting selects different second data to be transmitted.
