A plurality of sensors are combined with an integrated circuit to form a character recognition module and a plurality of such modules provide a device which can directly read embossed cards, such as conventional embossed credit cards. Advantageously, the pressure sensitive responsive means which respond to the movement of each sensing element comprises a pressure sensitive semiconductor region which changes electrical states to indicate the presence of a raised portion of the character sensed beneath the associated sensor. In each character recognition module, the respective pressure sensitive semiconductor regions are formed (preferably by doping) in their character recognition pattern on a single integrated circuit chip providing both the normal pressure sensitive electrical characteristics and additionally mechanical orientation and stability. The chip also includes, as an integral part thereof, the necessary logic circuitry and internal connected conductors to decode the change of state of the various semiconductor regions and thereby provide an output signal representative of the character being read. Means are provided such that the device will read different styles of display of the characters, commonly known as font styles.，下面是Embossment reader专利的具体信息内容。
