Technology Description |
|
| Infrared
light absorption analysis system. With a infrared sensors (emitter
and receptor), are analysed the different light absorptions or transmissions
at the banknote. This a technology where the fiability level depends
directly of the number of sensor, or is the same, depends of the machine
resolution. The commercial detectors has 8 sensors as maximum, whilst
a high resolution detector has around 100 sensors. |

Technology Disadvantage |
|
|
Need a mechanical
transportation for the infrared features detection.
High false alarm rate (greater than 1/100 with real street note).
This technology depends a lot with the state of the note, with new
notes the detector work well, but with used note the reject rate
growing up.
