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

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:
ADVANTAGES:

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.
