Let's start with the basics, namely, what do these acronyms actually stand for. RFID stands for Radio Frequency Identification and is a wireless, non-contact based technology that uses electromagnetic fields to automatically identify and track tags. These tags are often either attached to an object (e.g. vehicles, . See more
NFCor Near Field Communication is also a wireless technology, but, compared to RFID, it only enables short-range communication . See moreAs you can see from the differences between both technologies, each holds unique properties that are demonstrated in NFC and RFID access control. NFC is best used to securely transfer a range of data over short distances, hence its prevalence in access . See moreDespite both technologies appearing similar on the surface, there are 5 key differences between both technologies..

rfid nfc access control
Learn how to easily distinguish between RFID and NFC cards and understand the key differences in their technology and functionality.RFID access control systems work by having a reader next to a door detect the unique ID transmitted from an RFID card or key fob when it comes within a few feet. If the card ID matches what’s authorized in the access control system, the door will unlock. -Access control devices via cards or key fobs. -Inventory management systems to track item locations. NFC, or near-field communication, is a modern subset of RFID. You’ll often see NFC at work in smartphones for identification and payment capabilities.RFID-based access control systems come with physical key cards or key fobs. These are commonly known as tags, and each tag has a unique identification. The system manager can configure the access settings for each tag and then assign them to employees and visitors.
5 Key Differences: RFID VS. NFC. Communication Range: RFID: RFID operates over a longer range compared to NFC, typically ranging from a few centimeters to several meters. This extended range makes RFID suitable for applications such as inventory management and asset tracking, where the ability to read tags from a distance is essential. RFID cards — commonly called “tags” or “”fobs” — predate NFC technology. RFID cards interact with electromagnetic interrogation pulses given off by nearby RFID readers. The card transmits its token to the reader, which passes . Proximity Cards will typically use high-frequency radio waves, whereas Key Fobs can use passive radio waves, Bluetooth, or even Near-Field Communication (NFC). There are some basic nuances between these types of technology, but they all use close-range signals to transfer data from the card/fob to the reader.
Is NFC Better Than RFID? RFID, or radio frequency identification, is very widespread in the security industry. RFID antedates NFC and is often less expensive to implement. But does that mean it is better? NFC key fobs are smaller and, with the right encryption, can be more secure.RFID key fobs use a highly sophisticated process to exchange wireless signals. When the key fob enters the recognition range of the RFID reader, the reader emits radio waves of a certain frequency. The antenna on the key fob captures these .
