Dual Interface Smart Card Technology
One of the main advantages of the ACR1281U-C1 DualBoost II is its dual interface capability. Many traditional card readers only support one card technology, creating limitations for organizations that operate different smart card systems.
This reader combines both technologies in one device:
| Card Technology | Supported Standards | Typical Applications |
|---|---|---|
| Contactless cards | ISO 14443 A/B, MIFARE | NFC applications, transport cards, access control |
| Contact smart cards | ISO 7816 | Banking cards, government ID cards, authentication |
| Secure modules | SAM cards | Encryption and key management |
This flexibility makes the reader suitable for environments where users may need to authenticate with different types of cards.
Contactless NFC and RFID Card Support
The ACR1281U-C1 DualBoost II operates at 13.56 MHz and supports widely used contactless smart card standards.
