Compatible with Yoto. Ordering more...
I bought the MIFARE Ultralight EV1 cards and I'm very happy with them. The shipping was fast, arriving in 9 days, and there were no issues at all with customs. I tested all cards and they all work great. They're compatible with the Yoto player card clone technique, so that's ideal. I messaged the seller with a follow up question after purchase and he was very responsive. Definitely going to order more.
