Difference between RFID and Proximity Cards
The primary distinction between RFID and proximity cards is found in the scope of their technology and their applications. Below is a detailed explanation for clarity: RFID (Radio Frequency Identification) What it is: A broad technology that uses radio waves to identify and track tags attached to objects. Frequency ranges: Low Frequency (LF): ~125 kHz […]
Proximity Card Types
Proximity card types, often called “prox cards,” are a type of contactless smart card used primarily for access control. They use radio-frequency identification (RFID) technology to communicate with a reader, allowing for wireless data transfer. Here’s a breakdown of the common types and characteristics: Key Characteristics: Frequency: Most common proximity cards operate at a low […]
What is Proximity Cards?
Proximity refers to a type of access control technology uses proximity (or “prox”) cards and readers to allow or restrict entry to secure areas. The cards contain embedded radio frequency identification (RFID) technology, which communicates with a reader when brought within a certain range (typically a few inches to a couple of feet). Low frequency, […]
Type of Proximity Cards
Type of Proximity Cards are classified primarily by the frequency at which they operate. Based on Frequency: Low Frequency (LF) RFID: Operates at 125 kHz. Short read range (a few centimeters). Used for basic access control, animal identification, and proximity cards. Examples: HID Prox, Indala Prox. High Frequency (HF) RFID: Operates at 13.56 MHz. Longer […]
Proximity Cards
Proximity Cards are a type of contactless smart card used for access control and other applications. They operate at a frequency of 125 kHz and are typically used in conjunction with proximity readers. Key Features: Contactless Technology: No physical contact is required between the card and the reader. Low Frequency: Operates at 125 kHz. Limited […]
Proximity card
Proximity card, also known as prox card or key card, is contactless smart card that use radio frequency identification (RFID) technology to transmit data to a reader. This card commonly used for access control, time and attendance systems, and other applications where secure and convenient identification is required. How Proximity Cards Work: Radio Frequency Transmission: […]
