In Japan, a new payment system “Pay by swapping” has been launched. Currently, you can use this payment system on the travel website, so you can purchase a flight ticket by swapping something. When you want to use “Pay by swapping”, you’ll choose the branch and the category, and take a photo of the stuff you want to sell.
