We get this question a lot. The most economical ID scanner option is to buy an iPod 5 16GB (it now has a rear-facing camera) and get an ID scanning subscription from us.
You can get a used iPod on eBay for under $175, or a new one from Apple for $199. A month to month unlimited ID scanning subscription is only $19. Therefore, you can get set up for under $300.
A great price to protect your liquor license and become smarter about your customers.
