JASAG 100pcs Premium Rewritable UID Smart Card, Mi Fare 1K S50 RFID Cards Keys, 13.56MHz PVC Blank White JASAG-UID5050 JASAG-UID5050

Works great only downside is having to do it over 100 times for every Skylander

Good For Skylanders

Update:Yes! The UID IS REWRITABLE. This means sector 0, block 0 does change and CAN be reprogrammed. Phones are limited to this. It needs a card reader.Worked perfectly for Skylander's NFC. which I even tested successfully on my Nintendo Switch. I used with my android phone and mifare classic tool app to read and write to the tags. Very pleased.Yes, Imaginators creation crystals will work on these and it works with the NFC AC22 reader.Over 300 characters so I'll be purchasing again!

They work good but I ordered more and never received them on the date it said I would get them. The delivery date kept getting pushed back later and later. I ended up canceling them and ordering from a different place.

I was able to play through the entirety of Skylanders Giants with my twin brother and 19 Skylanders as well as Magic Items using only these cards and everything worked Perfectly!IT does take time to save data on the card though, so wait a while after you collect coins or XP or else the card will rollback but other than that it works well!

I bought these cards to use for making Skylanders NFC cards. A video I saw recommended these, and the description matched what I needed. Upon trying to use the cards and write a Skylander on the card, The card reached Block 63 out of 64 and failed stating that BLock 0 is not writable. Any help with this is greatly appreciated.(will change the review after receiving help)

For those looking for a great nfc card for skylanders look no further it works perfectly!

These cards are perfect for Skylanders!
