## Introduction to RFID ISO Cards


Radio Frequency Identification (RFID) ISO cards represent a significant advancement in identification and access control systems. These cards comply with international standards set by the International Organization for Standardization (ISO), ensuring interoperability, security, and reliability across various applications. An RFID ISO card utilizes electromagnetic fields to automatically identify and track tags attached to objects, with the card containing electronically stored information. Unlike traditional magnetic stripe cards, RFID technology enables contactless communication, making transactions and access control faster, more convenient, and more secure.

The technology behind RFID ISO cards has evolved substantially over the past decade, becoming integral to numerous industries including corporate security, transportation, payment systems, and inventory management. These cards operate on specific frequencies standardized by ISO, which helps in maintaining consistency and compatibility globally. Whether used for building access, public transportation, or payment processing, RFID ISO cards provide a seamless user experience while enhancing operational efficiency.


## How RFID ISO Cards Work


### Basic Principles of RFID Technology
RFID systems consist of three main components: the tag (embedded in the card), the reader, and the backend database. The RFID tag includes a microchip and an antenna, which communicate with the reader via radio waves. When an RFID ISO card is brought near a reader, the reader emits a radio frequency signal that powers the tag's chip. The chip then transmits its stored data back to the reader, which processes the information and communicates with a central system for verification or recording.


This process occurs without physical contact, allowing for quick and efficient data exchange. The ISO standards, such as ISO/IEC 14443 for proximity cards and ISO/IEC 15693 for vicinity cards, define the communication protocols, ensuring that cards and readers from different manufacturers can work together seamlessly. These standards also specify operating frequencies—typically 125 kHz The Use of RFID for Human Identity Verification
