How to scan some parts of the QR Code?

[Zikri_Zainal]

Hi,

I have lots of tools that are tagged such as the following

RC-B21-1-5
TB-R23-15-2
DR-R21-21-1

However, i want the scanner to only scan the code prior to the 2nd last ‘-’

So u would want

RC-B21
TB-R23
DR-R21

Can anyone help me this? Thank you!
