Hi Bhavin, the image you have sent to us has got too low resolution to be successfully read. Based on data you've sent us, we regenerated the high resolution image of the same barcode (available ). This high resolution image can be read with device that has got 480p video preview (Samsung Galaxy Ace). If a device does not support video preview of at least 640x480 resolution (preferably 1280x720), device will not be able to read such large barcodes. In order to successfully read the PDF417 barcode, each dot in barcode must be at least 1.5 pixels large in image. Best regards, Nenad. Hello Bhavin, if I understood correctly you were able to scan the barcode and obtain a string that is written inside barcode?
Our library just scans the barcode and returns its contents. The user of the library is responsible to interpret/decode the barcode data as they wish. Please note that we are currently preparing a parser for US driver's license PDF417 format and it should be available for purchase in the following months. Our free non-commercial version of the library just returns the data that is contained inside the barcode - it does not perform any additional parsing logic on the data. For more information about our library, please visit Best regards, Nenad.
Barcode technology is a popular method for states to store personal information on a driver's license. The new Georgia Driver’s License and ID cards include a PDF-417 barcode, which is supported by a wide variety of barcode scanner manufacturers. All the information printed on the front of a Driver’s License or ID is contained in the barcode. Magnetic Strip and Barcode Decoding. Drivers License Information. West Virginia.
Illinois was one of the few states to encrypt its drivers licenses, and as of May 2013 they stopped this practice. In an email from the Illinois Secretary of State they wrote: ' Since the information contained in the 2D barcode prints on the front of the card, the office made the decision to allow access. It allows other states, retailers and similar users to verify that the information on the face of the card has not been altered.' This is a great move and will prevent ' a drivers license to change the information. Good work Illinois!
