Abstract
Data exchange apparatuses and methods are provided. Two data exchange apparatuses are able to use a plurality of channels. One of the data exchange apparatus plays the active mode, while the other data exchange apparatus plays the passive mode. The active data exchange apparatus selects a first channel and transmits a data exchange request to the passive data exchange apparatus automatically through the first channel. The passive data exchange apparatus transmits an acknowledgment signal to the active data exchange apparatus automatically. Both the active and passive data exchange apparatuses select a second channel according to the acknowledgment signal and then exchange data through the second channel. People who owned a data exchange apparatus of the present invention can easily gather information according to his or her requirement from people who also own a data exchange apparatus.
