China's first signed e-signature contract made its appearance yesterday at the Science and Technology Exposition in Beijing.

The contract was signed between Beijing Zhongjiao Anda Transportation Technology Company and and US-based Tuanzhi Software Company.

Different from a traditional contract signing ceremony which involves paper contracts, general managers of the two companies each used a laptop computer and an special disk to sign the contract. After the password was placed in the system and the "Seal Button" clicked, the contract was chopped with each party's respective seals.

Because the e-signature system automatically records the user's name and log-in time, the contract can't be altered after it is signed, so e-signature contracts are deemed to be much safer than traditional contracts.
