MIFARE DESFire EV2 vs FeliCa Standard
MIFARE DESFire EV2 offers 2-32 KB memory with AES-128 + proximity check security, making it ideal for high-security transit, national ID, government. FeliCa Standard provides variable with 3DES mutual authentication security, suited for Japan/HK transit (Suica, Octopus), e-money, ID systems.

MIFARE DESFire EV2 vs FeliCa Standard
Both chips are deployed in high-volume transit systems with proven security records. EV2 adds relay attack protection; FeliCa provides higher transaction throughput. Geographic deployment determines which is relevant.
Overview
MIFARE DESFire EV2: ISO 14443ISO 14443Standard for contactless smart cards at 13.56 MHz (Types A and B)View full →-4, AES-128 + Proximity Check, 2–32 KB, 106 kbps. Dominant in European and global transit post-2013.
FeliCa Standard: NFC-F, 3DES, ~8 KB, 212/424 kbps. Backbone of Japan and Hong Kong transit.
Key Differences
- Speed: FeliCa at 424 kbps is ~4× faster than EV2 at 106 kbps. Japan's sub-200 ms gate requirement drove this design.
- Security: EV2 uses AES-128 (stronger than 3DES) and adds Proximity Check for relay attack protection. FeliCa uses 3DES without proximity measurement.
- Relay protection: EV2's Proximity Check actively defeats relay attacks. FeliCa has no equivalent.
- Geography: EV2 is the global standard outside Japan/HK. FeliCa is Japan/HK.
Technical Comparison
| Parameter | MIFARE DESFire EV2 | FeliCa Standard |
|---|---|---|
| Protocol | ISO 14443-4 (NFC-A) | NFC-F |
| Data rate | 106 kbps | 212 / 424 kbps |
| Memory | 2–32 KB | ~8 KB |
| Security | AES-128, Proximity Check | 3DES |
| Relay protection | Yes | No |
| Geography | Global | Japan, Hong Kong |
| Typical cost (volume) | $0.50–$1.00 | $0.30–$0.80 |
Verdict
Geographic context determines the platform. EV2 is the modern global transit standard with AES-128 and relay protection. FeliCa Standard is the Japan/HK transit platform with higher raw throughput but weaker modern security. Both remain in active large-scale deployment.
おすすめ
Choose MIFARE DESFire EV2 when you need relay attack protection via proximity check; choose FeliCa Standard when you need ultra-fast 212/424 kbps transaction speed.
