Abstract
A method for routing data in a chipset comprising at least one host processor and an RFID-type contactless data send/receive interface includes, in response to a command for opening a data path sent by a source point located in the host processor and designating a destination point located in the contactless data send/receive interface, defining a data path linking the source point to the destination point by allocating to the data path a routing channel number and by saving in a routing table the routing channel number and routing parameters comprising at least one identifier of the source point and one identifier of the destination point, and sending to the destination point data supplied by the source point by encapsulating the data in a frame having a header field comprising the routing channel number.
