A sensor for verifying value documents and designed to determine the luminescence time constant of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence time constant of the value document in the sensor. The relative movement between the value document and the sensor causes movement effects, resulting in a distortion of the intensity curve from which the luminescence time constant is derived. The luminescence time constant is corrected using a sensor-specific corrective factor ascertained for the velocity of the movement of the value document during the verification process. For this purpose, different sensor-specific corrective factors are used for different examples of sensors that are nominally identical in design and are part of the same sensor production series.

A sensor for verifying value documents is designed to determine a luminescence characteristic of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence characteristic of the value document in the sensor, resulting in a distortion of the measured luminescence intensities. A reference sensor is used to determine an average velocity dependency of the luminescence characteristic of a reference medium, said average velocity dependency being averaged over both opposite directions of movement and being used to determine a velocity dependency of a corrective factor for the luminescence characteristic. Said determined velocity dependency is used to determine the corrective factor for the luminescence characteristic, said corrective factor applying to the velocity of the movement of the value document during the verification process, and the luminescence characteristic is then corrected by said corrective factor.

Techniques for detecting counterfeit checks include using sensors to determine correspondence between a portion of sensed check information and related information; analyzing behavior related to accounts to a check deposit transaction; and controlling check depositing through user interface controls or communication. These techniques can be employed individually or in combination.
