Demo effect:

On-screen keyboards are very common in online life. For example, when using online banking or checking credit card balances online, the on-screen keyboard should be used when entering sensitive data such as passwords. To prevent Trojans or malicious programs from capturing and stealing actual keyboard operations. I hope this article can be helpful to everyone.
