Full machine-readable index: https://core-electronics.com.au/llms.txt # 13.56MHz RFID/NFC tag assortment - 1KB **Type:** Product page · **SKU:** ADA365 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia) **Page:** https://core-electronics.com.au/mifare-classic-13-56-mhz-tag-assortment-1kb.html ([markdown](https://core-electronics.com.au/mifare-classic-13-56-mhz-tag-assortment-1kb.html.md)) One of each of Adafruit's favorite 13.56MHz RFID/NFC Classic 1K tags - 5 in total! Credit card size 1" diameter 'laundry' clear tag 1" diameter 'laundry' white tag Key... ## Pricing - **Price:** $18.45 (inc GST) — $16.77 AUD, exc GST - **Quantity discounts:** 10+ $16.27 (exc GST) · 50+ $15.94 (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=ADA365:1` (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/ADA365:1.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 One of each of Adafruit's favorite 13.56MHz RFID/NFC Classic 1K tags - 5 in total! - [Credit card size](https://core-electronics.com.au/mifare-classic-13-56mhz-rfid-nfc-card-1kb.html) - [1" diameter 'laundry' clear tag](https://core-electronics.com.au/mifare-classic-13-56mhz-rfid-nfc-clear-tag-1kb.html) - [1" diameter 'laundry' white tag](https://core-electronics.com.au/mifare-classic-13-56mhz-rfid-nfc-white-tag-1kb.html) - [Key fob](https://core-electronics.com.au/mifare-classic-13-56mhz-rfid-nfc-clear-keychain-fob-1kb.html) - [Sticker](https://core-electronics.com.au/mifare-classic-13-56mhz-rfid-nfc-sticker-1kb.html) These can be read by almost any 13.56MHz RFID/NFC reader but make sure it can handle other cards as there are a few other encoding standards (like FeLica) They are tested and work great with both Adafruit's [PN532 NFC/RFID breakout board](https://core-electronics.com.au/pn532-nfc-rfid-controller-breakout-board-v1-3.html) and [Adafruit NFC/RFID Shield for Arduino](https://core-electronics.com.au/adafruit-pn532-nfc-rfid-controller-shield-for-arduino-extras.html)! **These chips can be written to** & store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writes. You can use Adafruit's [PN532 NFC/RFID breakout board](https://core-electronics.com.au/pn532-nfc-rfid-controller-breakout-board-v1-3.html) or [Adafruit NFC/RFID Shield for Arduino](https://core-electronics.com.au/adafruit-pn532-nfc-rfid-controller-shield-for-arduino-extras.html) to read and write data to the EEPROM inside the tag. There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another - **the ID number cannot be changed**. These use a ISO/IEC 14443 Type A chipset, which used to be the 'classic' NFC chipset. In ~2014, the NFC forum decided not to support this chipset anymore, **so newer phones do not support it**. This only matters if you're trying to use this tag with a phone/tablet. ## Technical Details RFID chip specification: - 1 KiloByte (8 KiloBit) non-volatile EEPROM storage - Built in encryption engine with 48-bit key - 4 Byte unique identifier burned into the chip - 13.56 MHz frequency ![](https://core-electronics.com.au/attachments/localcontent/rohs_icon_8216055e11.jpg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/3/6/365-00.jpg)
