Can the code scanning washing machine be cracked?

The self-service washing machine is either coin-operated or card-swiped. In fact, they all send startup signals to the computer board. If you can turn on the washing machine, it should be connected to a level. But it's best not to do this, it's improper behavior.

Self-service washing machines are divided into three categories: coin-operated, credit card-operated and online payment. With the progress of science and technology and the acceleration of people's life rhythm, self-service washing machines came into being. In Europe, America, Japan and South Korea, self-service washing machines can be seen everywhere. In our country's university dormitories, some have also installed such machines.

1. Pay by credit card: Generally speaking, smart washing machines consume by time, and the amount charged for each laundry is set in the system. The cardholder only needs to brush the inductive IC card in the effective range of the reading and writing area of the card reader. After hearing the beep, the laundry amount will be deducted, and the washing machine will start to work until the washing machine finishes this laundry. Cardholders can see the consumption amount and IC card balance through the display screen. If the balance of the IC card used is insufficient, or the validity period has expired, or the card has been reported lost, the system will send a prompt message to remind the operator to take corresponding measures. The principle of credit card payment is simple. According to the electronic system, the purpose of service is achieved by consuming the amount on the card.

2. Coin payment: When the washing machine is used, you don't need to make any choices after pressing the power switch. You only need to put coins (paper money) with the corresponding cost into the induction zone to start the washing machine to work normally. The working principle of this washing machine is that the control circuit is composed of various switches to control the voltage output of the motor, water inlet valve, water outlet electromagnet and buzzer, so that the washing machine can run the program.

3. Online payment: The washing machine adopts wireless payment system, so there is no need to exchange coins and buy cards. Just take out your mobile phone and scan the QR code on the machine, and you can start the machine through Alipay or online UnionPay. This form of payment is relatively new. At present, Ouba intelligent washing machine is used in the market.
