China UnionPay, one of the major payment processors, has recently patent a new blockchain-based system for connecting a network of automated teller machines (ATM’s).
Last month State Intellectual Property Office of the People’s Republic of China released a set of documents revealing a concept, under which ATMs are presented as nodes within a blockchain-powered network. All transactions are shared through a distributed database, which guarantees high level of security and operating time.
Regardless of using only limited amount of data coming from a single point of communication, which hardly seems to be reliable, the system is designed to maintain all transactional information in total security.
