Perkembangan teknologi saat ini memberikan kemudahan untuk melakukan segala sesuatu. Salah satu perkembangan teknologi terbaru adalah pada bidang komunikasi dan informasi. Salah satu teknologi terbaru dalam melakukan pertukaran data antar perangkat adalah teknologi NFC (Near Field Communication) adalah Teknologi berfungsi sebagai alat pengaman yang efektif dan efisien. Maka dalam penelitian ini dikembangkannya dengan menggunakan e-KTP sebagai gantinya dari NFC, sebagai otak dari sistem kendali ini digunakan Arduino Uno. Beberapa hardware yang dibutuhkan dalam pembuatan sistem ini adalah Arduino Uno, MFRC-522 RFID IC Card, e-KTP, Buzzer SFM-27 DC 3-24V, Relay 5V 2 Channel, Power Supply JC-36-12 Dc 12v/12, LCD 1602A SPI WITH I2C.Setelah seluruh sensor melakukan pembacaan, mikrokontroller arduino membuat instruksi untuk selenoid doorlock yang sumber tegangannya dari power supply dan terintegrasi melalui rellay dan di support oleh responden yaitu buzzer. Solenoid DoorLock dapat membuka dan menutup pintu gerbang ketika autentikasi yang dilakukan berhasil dan buzzer dapat menjadi alarm ketika autentikasi yang dilakukan tidak berhasil. LCD 1602A SPI I2C mampu memproses hasil masukan dari keypad, serta mampu memberikan masukan pada buzzer sehingga buzzer dapat berfungsi sebagai indikator peringatan dalam bentuk bunyi. Rellay mampu bekerja dengan baik untuk mengaktifkan pergerakan dari Solenoid DoorLock untuk membuka dan mengunci pintu. Sistem dapat membuka dan menutup pintu gerbang sesuai dengan rancangan yang telah direncanakan, yaitu dengan autentikasi RFID RC522 pada Arduino Uno.

Perkembangan teknologi yang semakin pesat menyediakan banyak kemudahan di dalam kehidupan manusia. Contohnya, kita menggunakan e-KTP untuk absensi ataupun untuk membuka pintu yang menggunakan komunikasi nirkabel untuk mencatat data atau untuk presensi. NFC (Near Field Communication) merupakan teknologi nirkabel terbaru, NFC secara khusus memiliki chip yang tertanam di smartphone android kita. Untuk membaca e-KTP memerlukan mikrokontroler Arduino Uno dan Sensor NFC PN532, Sensor NFC PN532 berfungsi untuk membaca ID e-KTP, dan Arduino Uno berfungsi untuk menampilkan ID e-KTP. Setelah itu ID akan di proses ke visual basic kemudian untuk ditampilkan ke web. Di Politeknik Pos Indonesia saat ini belum ada pencatatan data tamu yang menggunakan sistem otomatis, masih menggunakan sistem manual yaitu dengan cara menulis dibuku tamu, Dengan adanya teknologi tersebut diharapkan petugas pencatatan data tamu menjadi lebih mudah dan lebih cepat dalam proses pencatatan data tamu.

The phrase the Internet of things was originally coined in a 1999 presentation about attaching radio frequency identification (RFID) tags to individual objects. These tags would make the objects machine-readable, uniquely identifiable, and, most importantly, wirelessly communicative with infrastructure. This chapter evaluates RFID as a piece of mobile communicative infrastructure, and it examines two emerging forms: near-field communication (NFC) and Bluetooth low-energy beacons. The chapter shows how NFC and Bluetooth low-energy beacons may soon move some types of RFID to smartphones, in this way evolving the use of RFID in payment and transportation and enabling new practices of post-purchasing behaviors.

The Individual

The aim of this work is to tackle the problem of modulation wave shaping in the field of near field communication (NFC) radio frequency identification (RFID). For this purpose, a high-efficiency transmitter circuit was developed to comply with the strict requirements of the newest EMVCo and NFC Forum specifications for pulse shapes. The proposed circuit uses an outphasing modulator that is based on a digital-to-time converter (DTC). The DTC based outphasing modulator supports amplitude shift keying (ASK) modulation, operates at four times the 13.56 MHz carrier frequency and is made fully differential in order to remove the parasitic phase modulation components. The accompanying transmitter logic includes lookup tables with programmable modulation pulse wave shapes. The modulator solution uses a 64-cell tapped current controlled fully differential delay locked loop (DLL), which produces a 360° delay at 54.24 MHz, and a glitch-free multiplexor to select the individual taps. The outphased output from the modulator is mixed to create an RF pulse width modulated (PWM) output, which drives the antenna. Additionally, this implementation is fully compatible with D-class amplifiers enabling high efficiency. A test circuit of the proposed differential multi-standard reader’s transmitter was simulated in 40 nm CMOS technology. Stricter pulse shape requirements were easily satisfied, while achieving an output linearity of 0.2 bits and maximum power consumption under 7.5 mW.

Near-field communication (NFC) is a low-power wireless communication technology used in contemporary daily life. This technology contributes not only to user identification and payment methods, but also to various biomedical fields such as healthcare and disease monitoring. This paper focuses on biomedical applications among the diverse applications of NFC. It addresses the benefits of combining traditional and new sensors (temperature, pressure, electrophysiology, blood flow, sweat, etc.) with NFC technology. Specifically, this report describes how NFC technology, which is simply applied in everyday life, can be combined with sensors to present vision and opportunities to modern people.
