iCLASS 2050 vs. Seos 5266 — Which Smart-Card Credential
HID offers two main 13.56 MHz keyfob credentials. They serve different security tiers:
| Feature | iCLASS 2050 (this page) | HID Seos 5266 |
|---|---|---|
| Standard | ISO 14443 Type A | iCLASS SE / Seos platform |
| Memory | 2k / 16k / 32k bit | 8 KB |
| Encryption | Mutual authentication, 64-bit diversified keys | 128-bit AES, Common Criteria EAL 5+ hardware platform |
| Best fit | Mid-security commercial — most commercial offices, retail, residential | High-security — banking, healthcare, federal, FIPS-aligned environments |
For most Chicago commercial deployments, the iCLASS 2050 is the cost-effective smart-card upgrade off legacy 125 kHz Prox. For high-security or regulated environments, step up to the Seos 5266.
Reader Compatibility
The iCLASS 2050 reads on every HID iCLASS-family reader Vidimost installs in Chicago:
- HID iCLASS SE R10 — mullion smart-card reader
- HID iCLASS SE R40 — single-gang smart-card reader
- HID iCLASS SE R15 / R90 — additional iCLASS SE form factors
- HID multiCLASS SE RP10 / RP15 / RP40 / RPK40 — multi-tech readers that read iCLASS 2050 PLUS legacy 125 kHz Prox simultaneously, ideal for phased migration
