While bar codes because of its simple operation, fast speed information collection, information collection and other big advantage is widely used, but there are many potential obstacles and technical problems. This article will launch six bar code reader technology for content:
2. barcode character set encoding
3. The bar code scanning algorithm: localized and decoded
4. The development of small points: improved bar code recognition rate
The development of small points: increase the speed of the barcode recognition
Technical considerations point at 6. Select the barcode SDK
