The invention provides a downsized gas generator for a passenger side air bag which can supply a gas to the bag in time with the timing at which the reaction force is needed most for restraining of a vehicle occupant to be protected. The invention also provides antisense nucleic acid molecules, recombinant expression vectors containing 69039 nucleic acid molecules, host cells into which the expression vectors have been introduced, and nonhuman transgenic animals in which a 69039 gene has been introduced or disrupted. The internal receiving surface comprises a first wall portion having a first contact annulus and a second wall portion having a second contact annulus. The comparitor compares the scanned fingerprint with the file record fingerprint of the authorized card holder and if the fingerprints match allows the transaction to take place.
