## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE08497:1` (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/CE08497:1.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

This is a keychain-friendly RFID/NFC tag with an NTAG213 chip. The tag contains a small RFID chip and an antenna, which get passively powered by a nearby reader/writer.

Use these tags to create your own access control system, keep track of tools in your workshop or make a contactless vending machine. These tags can also be programmed with a special code that instructs the reader (eg. smartphone) to open a specific webpage, or navigate to an exact location on a map.

These can be read by almost any 13.56MHz RFID/NFC reader (or NFC enabled mobile-phone), since the NTAG213 standard is open source and avoids licensing issues present in older "Classic" cards (eg. MiFare).
