Bonus points earned through purchases on bank cards have long been an effective tool to attract and encourage customers to use specific cards. But since bonus points cannot be freely exchanged among different banks, offering various rewards, many go unused.

IBM’s collaboration with China UnionPay will enable consumers worldwide to exchange bonus points from their various banks in less than a minute to select rewards they want.

Block chain, the underlying technology in digital currencies such as bitcoin, has become one of the hottest innovations in the financial services world. Technology companies and banks have been exploring the use of block chain in all facets of both the financial and non-financial industries.

Dr. Shen Xiaowei, director of IBM Research-China and chief technology officer of IBM Great China Group said the company also is partnering with the Hyperledger Project to build a block chain platform and help clients develop more uses for industry.
