How does RFID technology differ from NFC as on mobile phones📱? How safe is the data that is stored on RFID keys once loaded onto the device? 🔐

At Copycat Keys we receive a range of questions from our customers, and requests to copy NFC key fobs. This article aims to explain the differences.

RFID (Radio Frequency Identification) and NFC (Near Field Communication) are two wireless communication technologies that are often compared due to their similarities. However, there are several key differences between the two technologies.

RFID uses radio waves to communicate between a tag or chip and a reader. RFID tags can be passive, meaning they don’t have an internal power source. ‘Active’ on the other hand means they have their own power source. RFID technology is typically used in supply chain management, inventory tracking, and access control systems.

NFC, on the other hand, is a subset of RFID that operates at a shorter range and uses less power. It allows two devices to communicate with each other when they are in close proximity, usually within a few centimeters. NFC is commonly used for contactless payment systems, mobile ticketing, and file sharing between devices.

Regarding the safety of data stored on RFID keys, it is important to note that RFID technology is vulnerable to unauthorised access if it is not properly secured. RFID chips can be read and copied by unauthorised readers. This could lead to the theft of sensitive information or unauthorised access to secure areas.

However, the security of NFC technology is generally considered to be more robust than RFID. Moreover, NFC includes additional security features such as encryption and secure element chips. When using NFC on mobile phones, the data stored on RFID keys is typically encrypted and secured using the same security measures used for other sensitive data on the device. As with any technology, it is important to ensure that proper security measures are in place to protect against unauthorised access or data breaches.
