Self-sufficiency product installment transaction platform system and method of self-sufficiency product installment transaction using the same {SELF-SUPPLY GOODS TRADING PLATFORM SYSTEM AND METHOD USING THE SAME}

The present invention relates to a self-sufficient product transaction, and more specifically, to a self-sufficient product installment trading platform system and a method for a self-sufficient product installment transaction using the same.

Recently, as the lifespan of mobile phones has increased, there are frequent cases of purchasing and opening used phones.

Used phones are also being traded at a considerable high price depending on the brand, and cases of damage are increasing as they are expensive products.

However, there is no means to safely trade used phones.

There are many websites for trading used goods, but until now, they are limited to the level of safe transaction using an escrow account, and there is no guarantee for the performance or durability of the used goods themselves.

The safety of the transaction itself can be sufficiently protected through the escrow transaction, but it can be seen that there is no means of protection against a minimum service life guarantee for expensive used phones or used goods.
