We are now sanitizing many laptops so, once in a while, we make mistakes when typing the id when tagging. Some of us (I personally do that once in a while) may swap codes form 12394 to 12943 or similar.
I know of two possible solutions for that and would like to know and share about them:
a) Add a Check digit-
b) Extract all the info with an USB connected to internet, sending the id number (previously sanitized, i guess) toghether with the Serial Number as well as other main laptop specifications. I am not sure this reduces errors as much as the other solution, but may be combined could lead to higher efficiency and reduce other errors such as the s/n.
Could you please explain these or other solutions and give your opinion and recomendations about them?
