CRM - QR Codes and Bar Codes

CRM - QR Codes and Bar Codes

Hi 
I am using CRM to run my service team - Asset maintenance business 

We need to move to and generate a QR code for each Asset we look after.  
And we need Bar code reading for the testing we do.
(pre-bar-coded sample bottles are provided by the lab)

Does anyone know how to do this please
