Probably just one of many nails to come on the CurrentC coffin:
Within the last 36 hours, we learned that unauthorized third parties obtained the e-mail addresses of some of our CurrentC pilot program participants and individuals who had expressed interest in the app. Many of these email addresses are dummy accounts used for testing purposes only. The CurrentC app itself was not affected.
We have notified our merchant partners about this incident and directly communicated with each of the individuals whose email addresses were involved. We take the security of our users’ information extremely seriously. MCX is continuing to investigate this situation and will provide updates as necessary.

Email addresses are fairly harmless, but not a great PR start for a system tied to your checking account, and that yes, actually requires your social security and driver license numbers to verify your identification.
