The present invention relates to a communication device (28) adapted to communicate with at least one second communication device (26) in a half-duplex near-field communication scheme, and to a method of near-field communication. According to the invention the first communication device (28) receives a first request message (30) from the second communication device (26) which is supposed to be answered within a first response waiting time span (bRWT), and which contains an amount of request data. The first communication device (28) sends within the first response waiting time span (bRWT) a second request message (34) to the second communication device (26), the second request message (34) representing a request for a second response waiting time span (RWT(m)) for providing a first response message (32) in reply to the first request message (30). According to the invention, the first communication device (28) ascertains a value of the requested second response waiting time span (RWT(m)), such that the value of the requested second response waiting time span (RWT(m)) generally increases with the amount of request data.
