Card processing system

A card processing system for use with a card, the card processing system comprising:

• a card reader structured to perform at least one of reading of data recorded in the card and recording of data to the card;
• and
• a host control section configured to control the card processing system,
• wherein the card reader comprises a card insertion part comprising an insertion port into which the card is inserted, and a control section configured to control the card reader,
• wherein the card insertion part comprises a light emitting part structured to emit light in plurality of colors,
• the card insertion part comprises a card insertion detection mechanism structured to detect whether the card is a normal card and is inserted into the insertion port in a correct posture,
• wherein the control section is connected with the host control section and is configured to perform light emission control which controls an emission color and an emitting method of the light emitting part,
• wherein the host control section is configured to specify a host-side combination of an emission color and an emitting method of the light emitting part and is configured to perform the light emission control,
• wherein the host control section previously sets a predetermined combination of an emission color and an emitting method based on the host side combination of the emission color and the emitting method,
• wherein the control section performs the light emission control based on the predetermined combination of the emission color and the emitting method, and
• the host control section is stored with a host side abnormality combination of the emission color and the emitting method, the host control section previously sets a predetermined abnormality combination of the emission color and the emitting method based on the host side abnormality combination of the emission color and the emitting method in the control section and, when a non-appropriate insertion of the card has been detected based on the detected result of the card insertion detection mechanism control section performs the light emission control based on the predetermined abnormality combination of the emission color and emitting method.
