Types of RFID Cards

RFID (Radio Frequency Identification) cards come in different types based on their frequency, chip technology, and applications. Here are the main types:

Types of RFID cards

Based on Frequency:

1. Low-Frequency (LF) RFID Cards (125 kHz)
   • Short reading range (up to 10 cm)
   • Commonly used for access control, animal tracking, and hotel key cards
   • Examples: EM4100, TK4100, HID Prox
2. High-Frequency (HF) RFID Cards (13.56 MHz)
   • Medium reading range (up to 1 meter)
   • Used in public transportation, payment systems, and NFC (Near Field Communication) applications
   • Examples: MIFARE, DESFire, NFC, iCLASS
3. Ultra-High Frequency (UHF) RFID Cards (860–960 MHz)
   • Long-range reading (up to 15 meters)
   • Used in supply chain management, logistics, and vehicle identification
   • Examples: EPC Gen2, Alien Higgs, Impinj Monza

Based on Chip Technology:

1. Read-Only Cards – Data is pre-programmed and cannot be modified.
2. Read-Write Cards – Users can update data multiple times.
3. Cryptographic Cards – Secure cards with encryption for authentication and secure transactions.

Based on Application:

1. Access Control Cards – Used for secure building access (e.g., HID, MIFARE)
2. Payment & Transit Cards – Used in contactless payments and metro systems (e.g., Visa PayWave, Oyster Card).
3. Hotel Key Cards – Programmed for temporary access
4. Employee & Student ID Cards – Used for authentication in workplaces and universities
5. Library & Membership Cards – Used for book checkouts and memberships
6. Vehicle & Toll Cards – Used in automated toll collection and parking access
