The microreader module (1) includes mounted and encapsulated on a first surface (44) of a substrate (40) a first reader integrated circuit (2) with control logic (3) and memorisation means (4), a second integrated circuit (21), such as a microcontroller with a transponder circuit, switching means (15) and a coil (L1). Several external contact terminals (43) are disposed on a second surface (45) of the substrate. At least certain of these external terminals are electrically connected through the substrate (40) to the encapsulated electronic components (2, 21, 15, L1). The microreader module can be configured in a reader mode or in a transponder mode by the same coil (I1) via the switching means (15) directly or indirectly connected to the coil. These switching means are controlled by a control signal (Sel) supplied by at least one external contact terminal (43). In this manner, the same coil can be linked to the first reader integrated circuit (2) when the microreader module (1) is configured in the reader mode, or connected to the second transponder integrated circuit (21) when the microreader module is configured in the transponder mode. The microreader module is realised under the compact shape of a surface mounting component of small size.
