The present subject matter relates to an item and related method and system for validating the authenticity of sensitive data respective to the item for associated processing on a high speed item transport device. The sensitive data associated with the item to be processed is exposed to energy, such as a particular range of light, for validation at high volumes while maintaining data anonymity; but the data is otherwise obscured from view by a filter material that blocks light outside the range. Furthermore, verification of the sensitive data is performed without necessitating significant mechanical configuration changes or item manipulation techniques.
