# RFID Reader ID-20LA (125 kHz)

**Type:** Product page · **SKU:** SEN-11828 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/rfid-reader-id-20la-125-khz.html ([markdown](https://core-electronics.com.au/rfid-reader-id-20la-125-khz.html.md))

RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-20LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing. Power the module, hold up a 125kHz card, and get a serial string output containing the unique ID of the card.

## Pricing

- **Price:** $62.70 (inc GST) — $57.00 AUD, exc GST
- **Quantity discounts:** 5+ $55.29 (exc GST) · 25+ $54.15 (exc GST) · 100+ $51.87 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 21 and Aug 24.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-11828:1` (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-11828:1.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)
