Photo ID
- Cost
- Speed
- Security
Cost
Cost considerations between the two are somewhat bipolar... while Photo ID Badging systems have a higher upfront cost, the readers utilized are less expensive. Also, ID cards can (and tend to be) lost... fingertips are not.
Speed
The speed differences between the two technologies is nominal. In the field, for example a cafeteria, it can take longer for a student to find, extract and swipe their ID card (assuming they have it) than to place a finger on a biometric scanner.
Security
Security is another double edged sword when considering the two. While a well designed Photo ID card will display the image of its holder, security lies in the hands of the cashier, for exmaple, scanning the card. Proper procedure dictates that the owner's image match both the image on the ID card and that on the computer screen.
Biometric scanning is, hands down, the more secure of the two.
