Handheld barcode readers has long become one of the most important devices in the Point of Sale industry. A CCD barcode reader works by illuminating visible red LEDs light onto a bar code. The CCD lens will then measure the ambient light from the bar code and send the signal to the sensors. A CCD barcode scanner works very well on small bar code labels, however, it isn't perfect. One of the main disadvantages of CCD barcode scanners is that they have poor reading performances under brightly lit area (ie. outdoors environments). In Addition, a typical CCD barcode reader usually cannot compete with a laser scanner in terms of their scan distance or so called "scan depth of field". A Handheld Laser bar code reader or "laser gun" uses a laser beam as a light source. As  the laser beam scan across the left/right edges of a barcode, a photodiode is used to measure the intensity of the light reflected back from the bar code and reflect laser light as TTL signal. In both pen readers and laser scanners, the light emitted by the reader is tuned to a specific frequency and the photodiode is designed to detect only this modulated light of the same frequency. Generally, a laser barcode scanner tends to be more expensive than a CCD scanner.

Fametech Inc. is an ISO-9002 certified manufacturer that  produces high quality products in the worldwide Automatic Identification and Data Collection (AIDC) market. All of our products are designed and manufactured in-house. Our barcode scanners come with Hand-Free Scanning or "Auto Scan" function that allows operators to scan barcodes without touching the trigger. This function has become a standard and popular feature in today's Auto ID market.

CCD bar code readers are among the key peripherals for process automation products. Contact-type CCD bar code readers must make physical contact with the surface of a bar code before scanning. In general, scanning is facilitated with the use of long-range, non-contact-type CCD sensors. Recent development trend favors the non-contact-type readers. Fametech Inc., (Tysso) for instance, has introduced long-range CCD bar code readers, the TS series, which scan at a distance of between 10cm and 40cm from bar codes.

In general, laser scanners can read bar codes from a longer distance than CCD bar code readers. Some companies develop laser scanners that are suitable special applications and specific working environments.  For instance, some industrial laser scanners such as Symbol P300PRO can scan a barcode label from a distance greater than three meters.

Fametech Inc.(Tysso) has more than 12 years of experience in OEM/ODM manufacturing CCD and laser barcode scanners. We are able to design and manufacture customized barcode modules as well as barcode decoders depending on customer's needs.
