A small percentage of cells within an established solid tumor have the properties of stem cells. These solid tumor stem cells give rise both to more tumor stem cells and to the majority of cells in the tumor that have lost the capacity for extensive proliferation and the ability to give rise to new tumors. The solid tumor heterogeneity reflects the presence of tumor cell progeny arising from a solid tumor stem cell. This discovery is the basis for solid tumor stem cell compositions, methods for distinguishing functionally different populations of tumor cells, methods for using these tumor cell populations for studying the effects of therapeutic agents on tumor growth, and methods for identifying and testing novel anti-cancer therapies directed to solid tumor stem cells.

In order to cause effective function when a system adopting a conventional settlement card is shifted to a system adopting a settlement card of IC card type and to enable a significant contribution to proliferation of the settlement card of IC card type, when a person who has input authentication data is authenticated as a user of a card by an authentication section, transaction data read by a magnetic stripe reader and transaction authentication data read by a memory reader are transmitted to a host server from transaction terminal equipment.
