ID Scanner is a free iPhone app developed by App Sub 1 LLC. It allows users to scan a driver's license using their phone's camera, eliminating the need for expensive hardware. With ID Scanner, you can easily check the validity and expiration status of an ID, among other features.

One of the key functionalities of ID Scanner is the ability to save a list of previous scans. This allows users to track and monitor who attended their venue or event within a specific time frame. By collecting aggregated statistics across the night, week, or month, businesses can drive marketing and promotional efforts more effectively.

ID Scanner also provides the option to create a VIP list or a Banned list. This feature enables businesses to keep track of their best customers and manage those who should not be allowed on their premises. Whether you own a bar, club, dispensary, or organize sporting events or town fairs, ID Scanner can help you become smarter in managing your customers.

It is important to note that ID Scanner does not save any information or photos from the app. All driver's license information is stored locally on the user's device and is automatically deleted when the app is uninstalled.
