Author

Tony L. Requena

This class can read barcode with ABBYY Cloud OCR service.

It can take a given barcode image and sends a HTTP request to the cloud OCR API Web server.

The class keeps polling the Web service every 5 seconds until the image is scanned and the barcode is decoded.

The class sets a variable with the processing results in XML.

PHP Programming Innovation award nominee

Number 3

Prize: One downloadable copy of PhpED Professional		 Barcodes are used to identify products of many types. However, if you need that a Web application identifies a product from a scanned barcode image, you need to be able to process the image to recognize the barcode that it contains.

This class can decode barcode images by sending them to a Web service that can understand and decode those images.
