OID is the abbreviation of Optical Identification, the cutting edge technology of optical indentifying application of connecting printing and electrical devices. OID coding is composed of an infinitesimal quantity of dots with different compositions presenting unique indexes. With the foregoing mentioning characteristics, OID reduces vision interference and keeps the esthetics for literature and drawings with excellent encryptions. OID is a low cost solution of enabling printings becoming electrical.SoniX OID technology and D.H.R.T have been granted of patents in the US, Taiwan, China, England, France and Germany . SoniX provides a chipset for image sensing. The SN9S102CE and decoder SN9P701FG is dedicated to OID. Considering optical characteristics, the OID index is up to 65,536. The visual interference coefficient is less than 1.5%, and the sensing angle is from 45 degrees to + 45 degrees. OID is applicable to operate under 10,000 Lux with less than a 1/1,000 error rate.
