There is a wooden box inside the doorway to Chinese University's business operations office.
For years, the office has used the box to collect written bids from suppliers for HK$100 million worth of tangible goods the New Territories university buys each year.
If some researchers in the university's engineering department have their way, this box, and others like, it will become obsolete.
David Yao and Houmin Yan said they started to build their 'e-jing'' electronic tender system, which was being given a commercial push by Chinese University's Centre for the Advancement of E-Commerce Technologies, about three years ago. Because of e-jing's ability to connect to backend enterprise resource planning (ERP) systems and to enable every step of electronic commerce from procurement to payment, Mr Yao and Mr Yan compared their software with packages offered by multinational companies such as Oracle, i2 and Ariba.
The university was using the system to take bids from 400 of its 1,400 suppliers.
One electronics firm had L signed on to use e-jing and others were under negotiation, the developers said.
