Acre Access Reader MT20S-I Black

The MT20S-I is a next-generation Multi-Tech card reader from ACRE in a Single Gang design, developed for professional access control systems and a smooth transition from traditional to modern authentication methods.

The reader combines 13.56 MHz NFC, 125 kHz Prox, and Bluetooth BLE 5.3, supporting both modern and legacy ACRE-approved credentials, including mobile credentials and Wallet solutions.

The MT20S-I communicates via OSDP V2.2 or Wiegand, and OSDP Autodetect enables a smooth transition to secure OSDP communication without altering existing wiring. An integrated EAL6+ Secure Element and accelerometer-based tamper protection provide high security. The reader features an RGB light indicator for clear status display and can be administered via Bluetooth.

The robust design is IP65 and IK07 rated, and the reader has a compact size of 133.4 × 83.6 × 18.5 mm. It is powered by 5–24 VDC, has a typical power consumption of 50 mA at 12 VDC, and a reading distance of up to 50 mm.

The MT20S-I is fully compatible with the previous generation of ACRE Multi-Tech readers and is suitable for both new installations and phased upgrades.
