Bidirectional Barcode Scanner ST-Q3

Bidirectional Barcode Scanner ST-Q3 — Access Control for Bahrain

The ST-Q3 reads access barcodes from both directions, so staff and visitors pass through without fussing over card orientation. It validates a credential in 200 milliseconds and reads from 0 to 20 cm, which keeps queues moving at a busy entrance.

It suits offices, warehouses, and residential complexes — anywhere you want barcode or QR-based entry without handing out physical keys. A green light grid lets it scan cleanly in the dark, and it holds up in Bahrain’s heat, rated from -20 to 70°C and up to 90% humidity.

Connection is flexible: RS-485, RS-232, and Wiegand let it drop into an existing access-control setup, and NFC support leaves room to move to smart cards later. Power draw stays low, and the LED indicators show the operator what’s happening at a glance.
