# RFID Glass Capsule (125kHz)

**Type:** Product page · **SKU:** SEN-09416 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/rfid-glass-capsule-125khz.html ([markdown](https://core-electronics.com.au/rfid-glass-capsule-125khz.html.md))

This is a glass, cylindrical RFID tag; it’s very similar to those implanted into pets for identification purposes. But really guys, it’s not for use inside your body. Please don’t implant this thing into yourselves. Each tag comes with a unique 32-bit ID code and is not reprogrammable. The carrier frequency of this tag is 125kHz, so it works great with our ID-3LA, ID-12LA and ID-20LA RFID readers.

## Pricing

- **Price:** $10.55 (inc GST) — $9.59 AUD, exc GST
- **Quantity discounts:** 5+ $9.30 (exc GST) · 25+ $9.11 (exc GST) · 100+ $8.73 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-09416:1` (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/SEN-09416:1.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
