1.ABSTRACT: This project proposes RedTacton based smart security card for ATM system. RedTacton is a Human Area Networking technology that uses human body as a safe high speed network transmission path. RedTacton uses minute electric field on the surface of the human body as a medium for transmitting the data. A transmission path is formed at the moment a part of human body comes in contact with RedTacton transceiver. RedTacton transmitter consists of a DTMF encoder which generates both valid and invalid signals and can be transmitted through human body to RedTacton receiver (DTMF receiver) for further processing. In order to enhance the security for ATM cards, RedTacton based smart security card is presented.

2.OBJECTIVE: The objective of this project is to give a better security system to transmit a data via body. Since there is no problem of hackers as our body itself acts as transmission medium and can be used more in the fields where there is a need to upgrade the security in times of high theft rate

WORKING PROCEDURE: Transmitter sends data Transmitting transceiver creates a change in the field Field from human body dissipates into earth Electric field is received using sensing technology Receiving transceiver recognizes the change in the electric field Sensing technology measures the weak electric fields induced. Electro-optical crystal uses laser to convert and read the signal

4.METHODOLOGY: This module consists of RedTacton transmitter, RedTacton receiver, Driver, ARM controller unit and the Voice bank. RedTacton is a HAN; body of human being is used for transmission of signals. RedTacton transmitter consists of a DTMF encoder which generates both valid and Invalid signals and can be transmitted through human body through the RedTacton receiver (DTMF decoder) for further processing. [4] In RedTacton receiver by the use of DTMF decoder the transmitted signal is identified. As the transmitted signal is of very low voltage, buffers and drivers are used to send the received signal to the electromagnetic switch. Electromagnetic switch checks the received signal with the predefined valid code.

If an invalid code is received and detected in the switch then the buzzer starts ringing indicating that an invalid card is trying to access the ATM. If a valid code is received, then only the switch sends the signal to the main control unit which is the microcontroller. If ARM controller gets active it switches on the keyboard where predefined options are stored to perform various tasks such as: Enter password, Change of password, New password, etc. After entering the valid password the voice bank gets activated. In voice bank predefined options with keys are present which guides the user to select appropriate action in the ATM such as: Cash withdrawal, Pin change, Account balance, etc…

5.ADVANTAGES AND DISADVANTAGES: RedTacton does not require the electrode to be in direct contact with the skin. Can transmit data at a rate higher than that of peer technologies. (max. of 10Mbps) and Security is more. RedTacton transceivers are programmable and we can decide what to share with whom and what devices you communicate with. Each communication occurs in separate channels. Transmission speed does not deteriorate even though the number of users increases. And More secure than Bluetooth. Data loss during transfer is less Use of minimum amount of power (of some milli -volt range) Superior than infrared technology & Wi-Fi

No problem of hackers. It is very hard to pick up stray electronic signals radiating from the body. DISADVANTAGES: The obvious barrier to entry is that the cost and time to develop HAN TECH. is very expensive.  As a new technology HAN need to gain popularity among users to help pull the technology into the marketplace instead of having it pushed upon them.   Widespread marketing campaigns will need to be developed to highlight the benefits of HAN technology to facilitate its adoption.  Not useful unless many people adopt it. It can be useful within few centimeters only.

6.APPLICATIONS: Automobile Applications Conference Systems Touch Advertising Wireless Headset This project can be used in Military, Medical and Consumer applications.

7.CONCLUSION: The proposed RedTacton based smart security card system for ATM has been implemented successfully and is tested on hardware. Experimental results verify the effective developed operation. When we compare RedTacton with other technologies, it can give a better security since there is no problem of hackers as our body itself acts as transmission medium and can be used more in the fields where there is a need to upgrade the security in times of high theft rate.
