BS900T
BS900T is the large-area fingerprint sensor of the BS family — a 252×350 array class at 500+ DPI, made for enrollment stations where a wide platen means the first capture is the good capture. MOQ is 1 pc, and the free SDK plus 48h FAE review make it a one-week bench project.

Enrollment stations, not enrollment choreography.
Industry channels count 19.8M biometric modules shipped a year, and the slice that survives an audit is captured once, at the desk. The BS900T was positioned for that moment:
- Wide 252×350 platen absorbs finger-position jitter, so a new operator registers on the first attempt instead of the fourth.
- POS vendor–ready — the same sensor library serves employee ID capture and customer loyalty ladders, so one bench supports two product lines (family class).
- MOQ 1 pc — pilot one desk, and only scale the chain when the numbers hold.
A collector with a record, not just a platen.
The registration desk is where identity quality is decided — the rest of the system only processes what was captured there. 300M+ cumulative algorithm-chip shipments across the EMS group stand behind the matching engine that reads BS900T images.
- 500+ DPI capture keeps minutiae detail intact for 1:1 re-checks during renewal.
- Unit-level test pass and a 2-year warranty cover every batch, including 1-piece orders.
- The FAE team reviews your reader schematic within 48h — matting, cover lens thickness, and controller pairing in one reply.
BS900T FAQs
Yes — 1 pc is the MOQ. A single sensor with datasheet and SDK ships in 1–3 days, and you keep the 2-year warranty.
The algorithm and SDK are part of the platform and free; the demo routine shows enrollment, 1:1 and 1:N over the UART host path.
BS-series controllers and AM160-class modules are the reference set; the FAE team confirms the matched list for your PCB within 48h.
