Connect site attendance with pay and claim records
A mobile site notebook prototype for Hong Kong subcontractors, using fictional sites, companies and people for interview demonstrations.
The business and its needs
The prototype explores how subcontractors and contractors review attendance, pay and claims. It is an undeployed interview demonstration, not a live payroll or legal calculation service.

-
Connected attendance, pay and claim demonstrations using fictional data.
-
Provided contractor views, with statutory items shown as reference and review prompts.
