In order to meet the above listed objectives and to implement the RFID based attendance authentication system using GSM concept the following architectures has been proposed and realized.
• By using PSoC microcontroller we can configure 2 full duplex UARTS at a time.
• One UART configured to collect the data from PSoC. Second UART configured to Communicate the PC.
• The flash memory of PSoC we can use as a EEPROM.
• The hardware complexity is also simple and we can reduce cost
