Design and implementation of advanced ARM7 based biometric security system using wireless communication

The important objective of this device is to increase an embedded device that is used for protection applications. In these systems, we are able to collect the client finger prints and mobile number at the same time as beginning the locker money owed then client most effective get right of entry to locker gadget. By placing the finger at the module while it get right of entry to automatically generates each time specific four-digit code as a message to the cell of the authorized purchaser through GSM modem connected to the microcontroller. The code obtained by way of the client have to be entered by means of urgent the keys at the keypad. After coming into it checks whether or not it is miles a valid one or now not and lets in the customer for further get right of entry to. In this project we are the uses of LPC2148 is main controller. It belongs to ARM7 structure. LPC2148 through Serial Interface. Also Biometric Module is attached to LPC2148. A 7805-3 terminal voltage regulator is used. Full wave bridge rectifier is used to convert the AC input of 230V to 12V with the help of step down transformer.
