Xiaomi has launched a pilot project to exchange old smartphones for new ones. The mechanism of the new service is that the user receives the estimated cost of his old smartphone on a special website, enters his IMEI, hands over the device and receives a coupon that can be used within two weeks to purchase a new Xiaomi smartphone. In the event that the desired device is more expensive than the face value of the coupon, the buyer pays for the difference in a convenient way, but if it is cheaper, the difference is not returned.
