Official MYO Yoto Card
Acts as a reusable bridge — you only need one MYO card total. Link a new playlist to it in the Yoto app, copy it to a blank, then repeat for the next card.
Printable Labels (optional)
Home-printable sticker labels sized to fit the cards. These ones print great right from your computer. Or just use a Sharpie!

Phase 1
Prepare the Blank Card
1
Send the NFC format command
In NFC Tools, go to Other → Send NFC Command. Paste the data below into the "Data" field, tap Send Command, then hold your blank card against the back of your phone.
A2:03:E1:10:06:00,A2:04:03:04:D8:00,A2:05:00:00:FE:00
2
Format the card memory
Still in NFC Tools, tap Format Memory, then hold the blank card to your phone again. This sets up the card's memory structure so it can accept Yoto data.
Phase 2
Copy the Yoto Content
3
Import from the official MYO card
After linking a playlist in the Yoto app to your MYO Yoto card, go to Write → More Options → Import from NFC. Tap your MYO card to read it. The app will load the card's data — then you can reuse the same MYO card for your next custom card by simply linking a new playlist to it in the app.
The official MYO card acts as the source — it bridges the Yoto app to your blank card.
4
Write to the blank card
Tap Write, then hold your blank NFC card to your phone. The content is now copied — the blank card is ready to use in your Yoto player!
Phase 3
Label the Card
5
Add a label
Design and print a label from your computer onto home-printable sticker sheets (linked in the supplies above), then stick it on. Or simply write the title with a Sharpie — both work great!
The Amazon labels linked above print well from home and fit the cards nicely.
💡 Good to Know
Why only those specific NFC cards? The command in Step 1 writes specific bytes to page addresses that only exist on the MIFARE Ultralight EV1 chip. Generic NFC tags have different memory layouts and won't respond correctly.
Why do you need the official MYO card? Yoto doesn't let you write directly to blank cards from the app. The MYO card holds the encoded track ID, and you're essentially cloning that identifier onto the blank card.
✅ Does this break Yoto's terms of service? Nope! This has been verified directly with a Yoto customer service rep — you're good to go. You're simply copying your own MYO card data to a different physical card, which Yoto is totally fine with.
