BASIC IDEA:

An ATM with a currency dispenser includes a contactless card reader. The contactless card reader can read data

from an NFC tag of a customer's ATM card. The contactless card reader, such as an NFC tag reader, can be

located so as to provide additional space for another transaction component. The contactless card reader can

also be used in conjunction with a magnetic stripe card reader. The ATM includes housing for the NFC tag

reader that is adapted to prevent interception of radio signals. The ATM is able to prevent dispensing of

currency in situations where unauthorized detection of signals is sensed.

Purposes

All of the cash dispenser cab be replaced to modern ones with NFC technology. Although, it is only for

contactless card recognition instead of mechanical card readers. Our project aim is to develop an application for

customers, they could use to manage faster their transactions without any interaction on the cash dispenser’s

interface. Even more importantly, blind people also could use it without restrictions.

What is NFC?

A basic NFC system consists of three components:

a) An antenna or coil

b) A transceiver (with decoder)

c) A transponder (RF tag)

Electronically programmed with unique information. There are many different types of NFC systems out in the

market. They are categorized according to their frequency ranges. Some of the most commonly used NFC kits

are as follows:

1) Low-frequency (30 KHz to 500 KHz)

2) Mid-Frequency (900 KHz to 1500MHz)

3) High Frequency (2.4GHz to 2.5GHz)

Data capacity

The amount of data storage on a tag can vary, ranging from 16 bits on the low end to as much as several

thousand bits on the high end. Of course, the greater the storage capacity, the higher the price per tag.

Security

Because this system works with personal data and money, so security is prioritized. The currently used credit

cards are EMV-compliant IC cards. EMV stands for Europay, MasterCard and Visa, a global standard for inter-

operation of integrated circuit (IC) cards, IC card capable point of sale (POS) terminals and automated teller

machines, for authenticating credit and debit card transactions. But this standard does not consider contactless

operations. This can be exploited e.g. by a rogue reader. There are well-known hacking methods available on

the Internet. For example NFCProxy, when card data are remotely transmitted. Therefore, I implemented

solutions for the following problems:

Contactless accesses should be authenticated

Contactless accesses should be encrypted

Contactless accesses should be ensured

The communication is encrypted between the NFC tag and the PC, so the transmission of cardholder data across

open, public network is safe. Furthermore the reader use strict time frames to avoid injections, like NFCProxy.

Typical Applications for NFC

Automatic Vehicle identification

Inventory Management

Work-in-Process

Container/ Yard Management

Document/ Jewelry tracking

Patient Monitoring

Advantages of NFC

No "line of sight" requirements: NFC tags can be read through materials without line of sight.

More automated reading: NFC tags can be read automatically when a tagged product comes past or near a

reader, reducing the labor required to scan product and allowing more proactive, real-time tracking.

Improved read rates: NFC tags ultimately offer the promise of higher read rates, especially in high-speed

operations such as carton sortation.

Greater data capacity: NFC tags can be easily encoded with item details such as lot and batch, weight, etc.

"Write" capabilities: Because NFC tags can be rewritten with new data as supply chain activities are

completed, tagged products carry updated information as they move throughout the supply chain.
