How to find out which type of barcode is this in my sample ?

  • 0

How to find out which type of barcode is this in my sample ? I looked on wikipedia and there are quite many types of barcodes, most common should be Code 39 and Code 128.

Is there any lib for barcode OCR (python, java, C#, delphi) ?

On this barcode should be encoded time and date of expiration.

EDIT

I need to know how to read and decode above barcode. This barcodes were generated in legacy system and It would be nice if my app could OCR and understand them

On my barcode should be date 19.11.2010 15:43

    According to this online bar code reader, it an EAN_13 code for a product with the number 5252235562500.

    According to Wikipedia it’s a product number for a discount coupon with manufacturer code 25223, family code 556 and coupon code 25.

    If there is an expiration date encoded in the data, it’s in some custom format encoded into the family code and coupon code. Otherwise you need a loopup table from the manufacturer to determine which coupon has which expiration date.
