The Mintit user interface uses artificial intelligence to help people upcycle their mobile phone through a kiosk installed at malls in South Korea. Traditionally, selling a used mobile phone has been a challenging experience due to disagreements between the buyer and seller over the phone’s condition and value. With the help of Mintit's AI and the remote dialogue user interface, users can easily check their phone’s condition, evaluate the buyback price, and instantly sell their phone at the kiosk. Since Mintit’s launch, more than 20,000 phones have been collected and recycled each month.
