I'm going to Carrefour as a cashier tomorrow. How can I identify fake money?

1. Cashiers who receive counterfeit money will compensate themselves

2. Generally, no one on the machine uses a laser pen to check the money, and all of them are manually checked

3. It is not easy to receive counterfeit money, but the money is a little old. Just pay attention when you collect it. If you find it, please ask the customer to change it, but you can't say "your money is fake". You should politely ask the customer to change it.

4. How to operate it, how to operate it correctly in case of emergency, and polite expressions

5. The specific shift time is different, so you can adjust it flexibly. The key is to find the person in charge.

6. Cashiers are absolutely not allowed to use mobile phones when they go to work.
