摘要 |
The invention relates to a reading device (5) for a chip card (10) comprising an electronic read-write device (15) having at least one antenna (20) for contactless reading data stored in the chip card (10) and for contactless writing data on the chip card (10) using electromagnetic waves (25) generated by the antenna (20) and a recess (35) on the front side for receiving the chip card (10) having a height corresponding to a multiple of the thickness of the chip card (10), wherein the antenna (20) is disposed in such a way that its electromagnetic waves (25) are injected into the recess (35). According to the invention, the antenna (2) is mounted in the area of a side wall (40) of the recess (35) with the purpose of enabling reliably reading and writing of the chip card in said reading device, even in the case of low transmitting power. |
