ABSTRAK

Near Field Communication (NFC), diartikan secara harfiah

Komunikasi Medan Dekat adalah seperangkat teknologi konektivitas nirkabel

berbasis teknologi Radio Frequency Identification (RFID) yang menggunakan

induksi medan magnet untuk memungkinkan komunikasi antar perangkat

elektronik dalam jarak yang dekat.

Pada Tugas Akhir ini, dirancang aplikasi pembaca dan penyimpan data

untuk sistem pembayaran. Pembacaan dan penyimpanan data dilakukan

menggunakan Reader ACR122U. Hal ini menjadi lebih mudah, karena aplikasi

yang dirancang terintegrasi dengan sistem authentikasi data dan enkripsi data

yang terhubung langsung pada sistem database server MySQL dan XAMPP.

Data dari Kartu Mifare akan sama seperti dalam database server yang dapat

ditampilkan pada computer/laptop.

Dari hasil pengujian, reader mampu membaca kartu Mifare pada jarak

0cm hingga 7,5cm. Data pada kartu Mifare pun dapat ditampilkan di form

aplikasi dan diintegrasikan dengan data yang ada di database server. Setiap data

yang berubah akan teratat dan terbentuk menjadi file .txt .

ABSTRACT

Near Field Communication (NFC), translates literally Near Field

Communication is a set of technology-based wireless connectivity technology

Radio Frequency Identification (RFID), which uses magnetic field induction to

enable communication between electronic devices in close proximity.

In this final project, designed reader application and data storage for the

payment system. Read out and data storage is done using ACR122U Reader. It

becomes much easier, because the application is integrated with the designed

system of data authentication and data encryption system that is connected

directly to the MySQL database server and XAMPP. Data from the Mifare card

will be the same as the database server that can be displayed on a computer /

laptop.

From the test results, Mifare card reader capable of reading at a distance

of 0cm to 7.5 cm. Data on the Mifare cards can also be displayed in the

application form and integrated with existing data in the database server. Any

data that changes will noted and formed into a file. Txt.

Types

Cards may be Type A and Type B, both of which communicate via

radio

at 13.56

MHz

. The main

differences between these types concern modulation methods, coding schemes (Part 2) and

protocol initialization procedures (Part 3). Both Type A and Type B cards use the same

transmission protocol described in Part 4. The transmission protocol specifies data block exchange

and related mechanisms:

1.

data block chaining

2.

waiting time extension

3.

multi-activation

ISO/IEC 14443 uses following terms for components:



PCD: proximity coupling device (the

card reader

)



PICC: proximity

integrated circuit card

Physical size

Part 1 of the standard specifies that the card shall be compliant with

ISO/IEC 7810

or ISO/IEC

15457-1, or "an object of any other dimension".

ISO/IEC 18092

1 Scope

This International Standard defines communication modes for Near Field Communication

Interface and Protocol (NFCIP-1) using inductive coupled devices operating at the centre

frequency of 13,56 MHz for interconnection of computer peripherals. It also defines both the

Active and the Passive communication modes of Near Field Communication Interface and

Protocol (NFCIP-1) to realize a communication network using Near Field Communication devices

for networked products and also for consumer equipment. This International Standard specifies,

in particular, modulation schemes, codings, transfer speeds, and frame format of the RF interface,

as well as initialisation schemes and conditions required for data collision control during

initialisation. Furthermore, this International Standard defines a transport protocol including

protocol activation and data exchange methods.

Information interchange between systems also requires, at a minimum, agreement between the

interchange parties upon the interchange codes and the data structure.

2 Conformance

A system implementing the Active and the Passive communication mode shall be in conformance

with this International Standard if it meets all the mandatory requirements specified herein.

It may also implement the NFC-SEC Option as specified in ISO/IEC 13157-1.

BAB I

PENDAHULUAN

Latar belakang, identifikasi masalah, perumusan masalah, tujuan,

pembatasan masalah, metodologi, spesifikasi alat, pembatasan masalah dan

sistematika penulisan dibahas pada bab ini.

1.1

Latar Belakang

Teknologi NFC adalah teknologi terbaru untuk

contactless smart card.

NFC memiliki protokol yang berbeda dibandingkan dengan

contactless MIFARE

dan memiliki keamanan lebih baik dibandingkan contactless MIFARE

[7]

.

Dalam Tugas Akhir ini akan dikembangkan sistem pembayaran dengan

teknologi NFC. Sistem akan menggunakan komputer dan NFC card reader

sebagai unit pendukung. Adapun Teknologi NFC merupakan seperangkat

teknologi konektivitas nirkabel berbasis teknologi RFID (Radio Frequeny

Identification) yang menggunakan induksi medan magnet untuk memungkinkan

komunikasi antar perangkat elektronik dalam jarak yang dekat.

[10]

Teknologi NFC itu sendiri akan diimplementasikan pada suatu sistem

pembayaran (point of sales) yang saat ini sudah menjadi kebutuhan yang penting

terutama bagi bisnis retail maupun pada umumnya, yang merupakan dengan

diimplementasikannya teknologi ini mampu memudahkan user dalam bertransaksi

secara aman, cepat, dan efisien, karena teknologi ini dapat memberikan berbagai

manfaat kepada user seperti intuitif : interaksi NFC tidak membutuhkan kesulitan

hanya dari sentuhan sederhana, versatile : NFC cocok digunakan untuk industri,

NFC pula telah mengikuti standar internasional yang diterapkan oleh
