Hi a different Code_39 barcode needs help

[bastrou]

Hi my company uses a barcode format Code_39 a little deferment that the usual it misses a few bars at the end. The above its my company's barcode and the other with the numbers is the usual.

I read that there is a class in zxing library
https://zxing.github.io/zxing/apidocs/com/google/zxing/oned/Code39Reader.html
that removes the necessity of this digits at the end.
Can you help in order to have access to her.

Thank you
