The invention discloses a portable
bank card number and code storage
machine, which is characterized by comprising a
data input module, a display module, a
fingerprint identification module, a
data treatment module, a
data transmission module, a
system resetting module and a
clock circuit. The
data input module is composed of a 4*4 keyboard; the display module is composed of an LGM12641BS1RLCD
liquid crystal display module and a 74HC245 three-phase latch; the
data transmission module is composed of an MAX232 and an RS232; the
fingerprint identification module is composed of an MBF310
fingerprint sensor and used for sensing fingerprint information and outputting digital signals to a controller; and a processor is composed of an AT89C51
single chip computer. Trough the portable
bank card number and code storage
machine, the security of the operation of banking businesses via an ATM (Automatic Teller
Machine) is greatly improved; and meanwhile, only a little fingerprint and
bank card information is needed to be stored in the
machine and the requirement on design is low, so that the portable bank card number and code storage machine has the advantages of low cost and easiness to spread to each family or person.
