BFM543E
BFM543E is the compact BFM-family capacitive fingerprint module for thin profiles — the variant that fits the fascia a sliding device leaves over, and the one payment-platform vendors route for shelf-friendly readers. MOQ is 1 pc; free SDK and 48h FAE response standard, photos on request.

The thin-profile fit is a whole-unit question — the FAE team checks the module envelope against your fascia drawing within 48h.
The fascia bends, the module doesn't have to.
Sliding-cover and slide-out units leave a portrait of available depth on the user-facing deck, and the reader is the first part the sheet-metal refuses. The compact variant keeps half the battle structural:
- Thin-profile body sits behind the fascia without a visible gasket curb (exact envelope on datasheet request).
- UART-class wiring can route inside the slide channel to the main board — no flex stack of last resort.
- 1-pc MOQ so the slide prototype is tested with the production part.
Where the shelf, not the safe, holds the identity.
Payment-platform vendors put the reader on the counter beside the terminal that settles the amounts — compactness is a placement requirement, and the family engine carries 400+ patents of group IP underneath a small face.
- Family-standard liveness-class checks on the capacitive front end (family class).
- Free SDK demo flow for enroll and verify; 48h FAE response for placement questions.
- 2-year warranty, and 1–3 day samples from a 1-pc order.
BFM543E FAQs
Yes — send the fascia drawing; the FAE team returns the envelope check with 1-pc terms inside 48h, and photos on request.
The BFM-family algorithm and SDK are free, with the counter-flow demo routine over UART included.
The exact envelope belongs on the datasheet — available on request; the family contract is the same UART footprint across BFM modules.
Fit first, quote second.
