Background Technology

[0002] With cash transactions still accounting for a significant portion of daily life, coins, as an important medium for small payments, are widely circulated in retail, public transportation, vending machines, and other fields. However, carrying and using large quantities of coins brings many inconveniences to users, such as their weight, volume, and difficulty in sorting them. Especially when it is necessary to exchange loose coins for banknotes, users often need to go to banks or specific exchange points, which consumes time and energy.
