Access Cards

Image
A Gateway to Security and Convenience Access cards have become an integral part of modern security systems, providing a convenient and secure way to control access to buildings, facilities, and restricted areas. These cards, typically the size of a credit card, contain a unique identifier that is used to verify a person's authorization to enter specific locations. Types of Access Cards Magnetic Stripe Cards: The earliest type, using a magnetic stripe on the back to store data. Proximity Cards: Utilize radio frequency identification (RFID) technology for contactless access. Smart Cards: Store more data and can perform complex operations. Biometric Cards: Combine card-based identification with biometric features like fingerprints or facial recognition. How Access Cards Work Card Reader : A device installed at entry points reads the card's information. Verification: The reader compares the card's data with authorized user records. Access Granted or Denied: Base...

RFID Smart Card Reader

Image
RFID (Radio Frequency Identification) smart card readers are devices that utilize electromagnetic fields to identify and track tags attached to objects. These readers are commonly used in various applications, including:    Access control: For granting or denying access to buildings, rooms, or restricted areas.   Time and attendance tracking: To monitor employee work hours.   Supply chain management: For tracking inventory and preventing theft.   Payment systems: As contactless payment cards.   Transportation: For public transport ticketing and toll collection.   Access Cards How RFID Smart Card Readers Work Tag Activation: The reader emits a radio signal that activates the RFID tag on the card.   Data Transmission: The tag responds by sending its stored data back to the reader.   Data Processing: The reader decodes the received data and processes it according to the programmed application.   Types of RFID Sma...
