Since official documentation from the UIDAI is very limited, we assume that data pertaining to transactions would comprise of the Aadhaar number, identifier of the authenticating device, date-time stamp, and approval/rejection/error code. Recording and maintaining of data pertaining to transactions is very important because it increases transparency and accountability through an audit trail. However, storage of such sensitive data creates many privacy risks, because more often than not metadata gives you as much intelligence as raw data.
