Abstract: An automated emergency assistance computing system may be configured to receive and store registration information about a mobile communication device user that may need help in connection with an emergency, including information about the type of the emergency. The system may receive an emergency alert from a mobile communication device through a communication network which indicates that a user of the mobile communication device is experiencing an emergency, including information about the location of the emergency. An emergency help request may be issued for help relating to the emergency. The emergency help request may include information about the location of the emergency, about the type of the emergency, and about how to communicate with the automated emergency assistance computing system to obtain continuous real time information relating to the emergency.

Abstract: The present invention relates to a method for authenticating financial transactions by using an additional factor which is not present on a physical card, and which is not used in sequential transactions. In one example, a purchaser provides card information to a merchant; the merchant transmits the card information and transaction information to an issuer; the issuer authenticates the card information, and transmits verification indicia to a target address associated with the card information. The purchaser target address may be the telephone number of a mobile telephone of the purchaser or a third party (e.g. parent). The purchaser or third party provides the verification indicia to a merchant; and the merchant transmits the verification indicia back to the issuer. The issuer authenticates that the received verification indicia relative to that sent to the target address, and thus the purchaser is the genuine or authentic person authorized to use card information; and the issuer approves the transaction.
