Frequency Ranges and Performance Metrics Passive RFID systems operate across distinct frequency bands, each offering specific advantages in read range and data transfer speed. Early generations of the technology were vulnerable to eavesdropping and cloning, where an unauthorized reader could intercept tag data.
Passive RFID Chip Vs Active: Understanding Key Differences
Their low profile and lack of batteries make them ideal for applications where size, longevity, and maintenance are critical concerns. Ability to store and update data securely on the chip itself.
Modern chips address these risks through sophisticated cryptography, implementing secure channels for communication and employing unique, tamper-resistant identifiers. Frequency Band Typical Range Key Use Cases Pros & Cons.
