## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DEV-14634:1` (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/DEV-14634:1.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)

## Description

The first new expansion board we have launched in 2018 is the NFC/RFID Expansion. This board will make use of the PN532 controller chip, which is the most popular NFC chip, and is embedded in pretty much every phone or device that does NFC. It can read and write to tags and cards, communicate with phones (for example payment processing), and ‘act’ like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use!

NFC (Near Field Communications) is a way for two devices very close to each other to communicate. It is an extension of RFID, so anything you can do with RFID you can do with NFC. You can do more things with NFC as well, such as communicate bi-directionally with cell phones. Because it can read and write tags, you can use this for RFID-tag projects.

I’ve prepared a short video demonstrating the new expansion reading a series of RFID card to determine if they are going to be accepted or not. This video is for you only, and not to be distributed.
