Abstract: A photolithography system has at least one spatial light modulator, a scanning mechanism configured to move an exposure area relative to a target object in a scanning direction, a plurality of memories (1st to Nth memories), a data processor, and exposure controller. The exposure area is defined as a projection area of the spatial light modulator. The plurality of memories corresponds to a plurality of partial exposure areas that is defined by dividing the exposure area. The data processor successively writes exposure data into each memory in accordance with the timing of an exposure, and the exposure controller controls the plurality of light modulating elements on the basis of the relative position of the exposure area. The data processor writes newly generated exposure data into the first memory, and shifts exposure data stored in the 1st to (N?1)st memories to the 2nd to Nth memories, respectively.

Abstract: An object of the present invention is to prevent a fraudulent use of a credit card such as spoofing. A server receives a card ID of a credit card, a credit amount, and a terminal ID for identifying a shop terminal from a shop terminal (S102), to start credit processing. The server acquires a corresponding user ID from the card ID (S104), to find out whether this user has approved that location information can be acquired from his/her mobile terminal (S106). In the case where the user has approved that location information is acquired in advance (OK at S106), the server acquires a mobile phone number from the user ID (S108), to know a location of the mobile terminal with use of this mobile phone number (S110). Area information of a base station in which the mobile phone resides is provided in the case where the mobile terminal is not equipped with a GPS function.
