Dual-frequency, multi-card RFID reader
One Arc reads both low-frequency 125 kHz and high-frequency 13.56 MHz credentials. EM, MIFARE, MIFARE Plus, DESFire, DESFire EV1 and FeliCa cards work on the same reader, so the cards already in circulation keep working while new ones are rolled out.
Connects to the panel you already have
The Arc brings card, NFC and BLE credentials into one reader and passes each read to the controller over RS-485 or Wiegand. It works with access control panels and third-party controllers alike; existing wiring stays as it is.
Secure reader-to-controller link: OSDP
The Arc speaks Open Supervised Device Protocol (OSDP), the open industry standard for connecting readers to controllers over RS-485. Unlike the one-way, unencrypted Wiegand line, OSDP is bidirectional, encrypted and continuously supervised.
- EncryptedSecure Channel with AES-128
- Two-wayThe controller drives the LED and buzzer and reads reader status
- SupervisedA cut or tampered line is reported to the controller
Your phone is the key
No card needed: the Arc reads mobile credentials over Bluetooth and NFC. Every exchange is AES-encrypted.
- BLEBluetooth Low Energy on Android and iOS
- NFCHCE on Android, supported by most current phones

Where it runs

The hardware changes at the edges. What stays the same is how it is designed: for installers who have to make it work on a site that already exists.
