It seems that many coffee shops don't need certificates. Want to know if the barista certificate is useful?

Generally, professionally trained baristas have certificates, which are equivalent to academic qualifications if they are useful. At present, the state of coffee shop is only skilled operation. It is suggested that you take a barista certificate if it is convenient, so that you will be guaranteed when you meet a demanding coffee shop in the future. It's really not very useful. I have three years' experience as a barista and have never participated in barista training and competition, so it is no problem to start as a coffee apprentice. Experience is the most important thing.
