### How RFID Membership Cards Work
RFID membership cards contain a tiny microchip and antenna embedded within the card structure. When brought near an RFID reader, the chip receives power from the reader's electromagnetic field and transmits stored data wirelessly. This technology enables:
- Contactless access control to facilities
- Quick member identification at events
- Integration with point-of-sale systems
- Attendance tracking and analytics
- Multi-application functionality on a single card
### Types of RFID Cards Available
**Low Frequency (LF) RFID Cards:**
- Frequency: 125 kHz
- Read range: Up to 10 cm
- Common applications: Basic access control, animal identification
- Chip examples: EM4100, T5577
**High Frequency (HF) RFID Cards:**
- Frequency: 13.56 MHz
- Read range: Up to 1 meter
- Common applications: Membership cards, payment systems, public transit
- Chip examples: NXP MIFARE Classic 1K (S50), MIFARE DESFire EV2, NTAG213
**Ultra-High Frequency (UHF) RFID Cards:**
- Frequency: 860-960 MHz
- Read range: Up to 12 meters
- Common applications: Inventory management, long-range access control
- Chip examples: Alien Higgs-3, Impinj Monza R6
*Technical Note: The MIFARE DESFire EV2 chip features 2KB/4KB/8KB memory, AES-128 encryption, and supports multiple applications. Card dimensions typically follow ISO/IEC 7810 ID-1 standard: 85.6 × 54 × 0.76 mm. These technical parameters are reference data only; specific requirements should be discussed with our后台管理 team.*
