Abstract
Methods and systems for generating an identifier include detecting emissions from a phosphor pattern with a sensor grid comprising one or more sensors when the phosphor pattern is stimulated with radiation. An output signal of each sensor in the sensor grid is compared to a threshold value to generate respective identifier bits. An identifier is generated from the identifier bits.
