The securities clearing house will launch Hong Kong's first electronic initial public offering (IPO) within six months.
The development means investors will be able to apply for new share offers over the telephone instead of having to queue for subscription forms.
Hongkong Clearing chairman John Chan Cho-chak said all investors who had an account with the Central Clearing and Settlement System (CCASS) would be able to use the service.
Allotted shares would be transferred to accounts in CCASS, while payments and refunds would be transferred from or to the investor's bank account.
Investors without a CCASS account could continue to use traditional methods of subscription, Mr Chan said.
There are 1,860 investors who have opened individual accounts with the central clearing system since the service was launched in May last year.
