Core Technology



Our core technologies are based on Security Printing Technology of bank notes. According to the unique know-how, "SPT", V&T has developed the other two core technologies "Optical Inspection Device" (OID) and "Programmable Detecting Chipset" (PDC).

The OID reads the data from the optical inspection sensors and transmits this data to the PDC. The PDC determines whether the banknote is real or forged, and controls the mechanical structure and circuits to take appropriate action.



Normally, 3-D verification consists of:
SPT : Security Printing Technology.
PDC : Programmable Detecting Chipset.
OID : Optical Inspection Device.
