13.56MHz RFID IC Key Tag

Product Description The 13.56MHz RFID IC Key Tag is a durable and portable proximity token designed for secure access control and identification systems. This tag operates on the high-frequency (HF) 13.56MHz band and is fully compatible with Mifare S50 standards. Each tag contains a pre-programmed 4-byte unique ID (UID) and 1KB of rewriteable memory organized into sectors, allowing for encrypted data storage. Encased in a rugged, waterproof ABS plastic shell with a convenient keychain loop, it is the perfect solution for apartment security, office time-attendance, loyalty programs, and automated cabinet locking. It works seamlessly with popular RFID reader modules like the RC522 and PN532.

Key Features

• High-Frequency Operation: Operates at 13.56MHz, offering faster data transfer and higher security compared to low-frequency 125KHz tags.

• Rewriteable 1K Memory: Features 1024 bytes of EEPROM, allowing you to store and modify user data, credits, or access logs directly on the tag.

• Unique Identification: Every tag comes with a factory-set 4-byte UID, ensuring no two tags in a basic system are identical.

• Rugged & Waterproof: The ultrasonic-welded ABS casing protects the internal antenna and chip from moisture, dust, and mechanical impact.

• Universal Compatibility: Works with any ISO 14443A compatible reader, making it a standard choice for Arduino and Raspberry Pi projects.

Technical Details

• Chip Architecture: Based on the classic 1K S50 structure with 16 sectors, each protected by two sets of keys (Key A and Key B).

• Passive Technology: No internal battery required; the tag draws power through inductive coupling from the reader's magnetic field.

• Read/Write Speed: Capable of high-speed data transmission up to 106 kbit/s.

• Anti-Collision Support: Intelligent anti-collision function allows multiple tags to be present in the reader field without signal interference.

• Security Features: Individual sector keys and access conditions provide a high level of security for payment or sensitive entry systems.

• Keyring Design: Includes a sturdy metal ring, making it easy to attach to keys, lanyards, or employee ID badges.

• Standard Compliance: Fully compliant with ISO/IEC 14443 Type A specifications.

• Resonant Frequency: Precisely tuned internal coil ensures maximum read distance even through thin fabric or plastic.

• Storage Organization: 16 sectors of 4 blocks each; one block is 16 bytes.

• Write Endurance: High-reliability memory allows for 100,000 rewrite cycles per block.

• Chemical Resistance: ABS shell is resistant to common cleaning agents and sweat.

• Operating Range: Peak performance achieved at 2cm-5cm; maximum range of 10cm depending on reader antenna power.

• Logic Isolation: Electrical interference between sectors is eliminated by independent encryption keys.

• Fast Authentication: Mutual three-pass authentication protocol for secure data handling.

• Lightweight Build: Designed for everyday carry without adding bulk to a user's keychain.
