JCB Co., a credit card and payments firm based in Japan, said it entered an agreement with Keychain, a blockchain technology provider, to leverage blockchain in the payments sector. 

JCB said it will use Keychain's technology to increase cyber security and operational integrity in next-generation payments systems, according to a company release. 

Keychain, based in Singapore, has been working on a new global data security structure in recent years. The firm has a product called Keychain Core, which allows partner firms to build applications with self-sovereign identity and data centric security. 

The technology works on a range of devices, including tablets, computers, smartphones, smart watches and other devices.
