It's easy to use and more affordable than ever! ## Pricing - **Price:** $35.95 (inc GST) — $32.68 AUD, exc GST - **Quantity discounts:** 10+ $31.70 (exc GST) · 50+ $31.05 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Sep 03 and Sep 07. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4690:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4690:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. It's easy to use and more affordable than ever! These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. It comes with an 8-pin 1mm pitch connector with 0.1" header sockets for plug-and-play with a breadboard or dev kit. You can also easily cut off and solder directly to the wires. The cable is color-coded so it's easy to wire up: - Red is 3.3V power - Yellow is TTL Serial TX - White is TTL Serial RX - Black is Ground But, of course, Adafruit wouldn't leave you a manual and a "good luck!" - Adafruit have written both an [**Arduino library**](https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library) and [**CircuitPython library**](https://github.com/adafruit/Adafruit_CircuitPython_Fingerprint) so that you can get running in under 10 minutes. The library can enroll and search so it's perfect for any project. [Adafruit have also written a detailed tutorial on wiring and use of these types fingerprint sensors](https://learn.adafruit.com/adafruit-optical-fingerprint-sensor). ## Guides for this product - [Fingerprint Scanner with Raspberry Pi Single Board Computer - Unlock with Biometrics!](https://core-electronics.com.au/guides/raspberry-pi/fingerprint-scanner-raspberry-pi/) ## Videos for this product - [Fingerprint Scanner with Raspberry Pi Single Board Computer - Unlock with Biometrics!](https://core-electronics.com.au/videos/fingerprint-scanner-with-raspberry-pi-single-board-computer-unlock-with-biometrics) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/4/6/4690-02.jpg)
