POCS (Point of Chain Sales, payment chain) is a digital asset issued by the Singapore China Chain Foundation based on the Ethereum ERC-20 protocol. Committed to changing the status quo of the domestic third-party payment industry, improving the order of the domestic bank card acquiring environment, and increasing the stickiness of the collection terminal to merchants. The POCS payment chain uses tokens to solve the problem of information asymmetry between the upstream and downstream channels of the payment industry (that is, the fee income returned by the payment institution), so that the channel service provider's profit sharing data can be decentralized and cannot be tampered with, and a consensus of trust can be achieved . At the same time, the payment terminal (mining machine) used by the merchant can not only meet the normal payment needs of the merchant, but also give the merchant a certain amount of token rewards to encourage the enthusiasm of the merchant to swipe the card. Turn the card-swiping machine for payment into a "mining machine", and make the card-swiping transaction a "mining" behavior.
Point of Chain Sales (POCS) is an ERC20-based smart contract token. POCS is a reward for all participants in the entire payment ecological chain, and users can freely trade after obtaining tokens.
