What is the purpose of an ID reader?

ID readers are commonly used in various settings such as bars, nightclubs, and retail stores to quickly and accurately retrieve information from IDs. By scanning the barcode or reading the magnetic stripe, an ID reader can provide access to relevant data such as the person's name, age, and other pertinent details stored on the ID card. This helps verify the identity and age of the individual, especially in situations where age verification or access control is required.
