Having a unique ID# distinct from the SSN prevents one from mapping a name and DOB to the SSN without access to the linking information. This is one technique used in clinical trials to depersonalize information so that I can't use the information about a person to identify them. This would not prevent a legitimate user of the card from accessing your SSN using a single swipe of the card, as this information would presumably be mapped in a database on the back end.
I recall the left arguing adamantly against any sort of forced ID card when it was suggested as a way to prevent voting fraud, saying that it was only a way to disenfranchise the working poor who honestly couldn't afford to take the time or money to go obtain one.
