Selection guide
| Use case | Recommended option | Notes |
|---|---|---|
| Common HF card systems | MIFARE or compatible HF card options | Confirm exact chip and reader compatibility before production. |
| Fudan chip projects | Fudan card options | Use when the project specifies a Fudan chip or compatible system requirement. |
| Special chip requirements | Other chip card options | Share the reader, standard or existing card details so the chip can be matched. |
| Unsure chip type | Start with reader compatibility | The reader system normally determines which chip family should be used. |
| Higher-security or multi-application projects | MIFARE DESFire EV1/EV2 chip options | Choose when the project needs AES encryption or multiple applications on one card beyond basic MIFARE Classic. |
| Long-range UHF tracking | UHF chip card options (860-960MHz) | Confirm the required read range and reader frequency band before selecting a UHF chip. |
| NFC smartphone tap-to-read | NTAG-based HF chip cards | NTAG chips are widely supported by NFC-enabled smartphones for consumer-facing tap-to-read use cases. |
| Hybrid dual-frequency projects | Dual-chip / dual-frequency card options | Combines two chip families (e.g. LF+HF) on one card body; share both reader requirements for a match. |
FAQ
How do I choose an RFID card chip?
Start with your reader system, existing card type, required frequency and application. The chip should be confirmed before artwork or card production.
Are all RFID card chips compatible with all readers?
No. Reader compatibility depends on frequency, chip family, protocol and system configuration.
Can ZealTag supply different chip card options?
ZealTag can help compare suitable card chip options based on your project details. Share the reader model or required chip if available.
Can chip cards be custom printed and encoded?
Custom printing and encoding may be available depending on chip type and data requirements. Provide your artwork and encoding needs for confirmation.
What's the difference between MIFARE Classic and MIFARE DESFire chips?
MIFARE Classic uses simpler proprietary security and is common in basic access control and membership cards. MIFARE DESFire EV1/EV2 uses AES-based encryption and supports multiple applications on one card, suited for higher-security or multi-use projects. Confirm which family your reader system supports before ordering.
Can different chip types be produced in the same order?
Yes, different chip types can be produced as separate SKUs within the same order, but each chip type is manufactured and tested individually. Share your quantities per chip type for an accurate quote.
What are dual-frequency or dual-chip cards?
Dual-frequency cards combine two chip families, such as LF and HF, on a single card body for hybrid use cases like access control plus payment or tracking. Contact us for available chip combinations.
How do I know which frequency my chip needs?
Frequency is usually determined by your existing reader infrastructure: LF (125kHz) is common for older access control systems, HF (13.56MHz) covers MIFARE and NFC-based systems, and UHF (860-960MHz) is used for longer-range tracking. See our RFID card frequency guide for a full comparison.
