13.56 Mhz RFID Card

13.56 Mhz RFID Card
These cards operate using the ISO 14443A protocol. When brought near a 13.56MHz reader, the card’s internal antenna harvests energy via magnetic induction. This powers the internal chip, which then engages in a high-speed, encrypted handshake with the reader to exchange data.

Why it’s a Secure Systems Essential:
• Sector-Based Memory: The 8Kbit memory is divided into 16 sectors, and each sector is further split into 4 blocks. Each sector can be protected by its own unique Key A and Key B. This allows one card to be used for multiple purposes (e.g., Sector 1 for door access, Sector 2 for canteen payments) without the systems interfering with each other.
• Encrypted Communication: The card supports mutual authentication and data encryption. This makes it significantly more difficult for unauthorized devices to "sniff" or clone the card compared to older 125kHz technology.
• Wallet-Friendly & Printable: The standard CR80 size (credit card size) and smooth PVC finish make these cards perfect for carrying in a wallet. They are also compatible with thermal card printers, allowing you to print high-quality photos and text directly onto the surface.
• Fast Transaction Speed: With a communication speed of 106 kbps, a full read/write cycle takes only 1–2 milliseconds, ensuring that users aren't delayed at turnstiles or access points.

Technical Capabilities:
• Frequency: 13.56 MHz (HF).
• Memory: 8 Kbit / 1 KB EEPROM.
• Read/Write Endurance: > 100,000 cycles.
• Operating Distance: 2.5 cm to 10 cm (Antenna quality on the reader is the primary factor for distance).
• Anti-Collision: Built-in logic to ensure the reader can identify this specific card even if multiple cards are held together.

Best For:
The 13.56MHz Smart Card is the primary choice for multi-factor authentication, biometric ID cards, stored-value payment systems, and secure hospital/government access.
