Sorry I have to answer in English, it will be much easier for me.
You cannot translate bar code unless you specify which kind of bar code you want to translate to. like if i ask a question can you translate this message? The answer is "NO" unless you specify i want to translate it into Chinese or Japanese... something like that.
There are quite a lot of barcode format around, basically they can be divided into 2 different type, 2 dimension (2D) and 3D barcode.
2D for example there is 39 code, 2-5 interleave, EAN, UPC... and much more. 3-9 code is comparatively long however it can "translate" from number (0-9) or English letters (A-Z), 2-5 interleave is shorter but it can only be used in code "number", EAN is the retail barcode widely used in Europe and Asia while UPC is used in USA.
3D barcode including PDF417 and QR code, which were used to put more information in a smaller area or they can made to contain capability of error correction, ie it can be read even part of the pattern is damaged by scratch of cover by dirt. These code can code even picture inside (like yr SAR passport).

many books include sub-routine (usually in C or BASIC) you can use to o/p simple barcode, if you have some software experience you can import or translate them. you can also find some free staff for QR code, however PDF417 was patented so nothing is free . good luck in yr project.
