Hand-held barcode scanner. Handheld scanners are the product of the technology that was introduced in 1987, and the shape is similar to the barcode scanners used by the supermarket cashier in hand. The majority of the bar code scanners using CIS technology, optical resolution of 200dpi, there are black and white, grayscale, color a variety of types, of which the color type is generally 18-bit color. Also have individual high-grade products using CCD as a photosensitive device, can realize bit true color, scanning effect is better.


Second, small drum type barcode scanner. This is a handheld barcode scanner and platform-type barcode scanners in the middle of the product (in recent years there is a new appearance, because it is built-in power and small size is called Notebook barcode scanner) The majority of this product using CIS technology, optical resolution of 300dpi, there are two color and gray, color models generally 24-bit color. There are also a few small drum-type barcode scanners using CCD technology, scanning effect is significantly better than the CIS technology products, but due to structural constraints, the volume is generally significantly larger than the CIS technology products. Small roller design is the barcode scanner lens fixed, and move to scan the object through the lens to scan, operating like a printer, to scan the object must be sent through the machine, so the scanned object can not be too thick. The biggest advantage of this barcode scanner is that the volume is small, but due to the use of a variety of limitations, such as only scanning thin paper, the range can not exceed the size of the barcode scanner.


Third, the platform-type barcode scanner. Also known as flat-panel barcode scanners, desktop barcode scanners, currently in the market most of the barcode scanners are plate-type barcode scanners, is now the mainstream. This type of barcode scanner optical resolution between 300DPI-8000DPI, the number of colors from 24 to 48, scanning format is generally A4 or A3. The advantage of the tablet is that, like using a copier, the top cover of the barcode scanner can be turned on, whether it is a book, newspaper, magazine or photographic film, which is quite handy, and the effect of the scan is the best of all the common types of barcode scanners.


There are also large-area scanning large-area barcode scanners, pen barcode scanner, barcode scanner, film barcode scanner (note is not a flat bar code scanner plus sweep, the effect is much better, the price is also expensive), physical barcode scanner (not have the physical scanning ability of the flat bar code scanner, a bit like a digital camera), There are mainly used in the field of printing and typesetting of the drum-type barcode scanners and many other.
