Worked fantastically on my NFC Reader. The ACR one. ### ⭐⭐⭐⭐⭐ Skylanders *by S***1 on December 21, 2025* The cards work well for skylander figure substitudes. ### ⭐⭐⭐⭐⭐ Worked for Skylanders, tested with Nintendo Switch, Block 0 Writeable *by C***Y on November 30, 2024* 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! ## Frequently Bought Together - TO BE SECOND JASAG 100pcs Premium Rewritable UID Smart Card, Mi Fare 1K S50 RFID Cards Keys, 13.56MHz PVC Blank White JASAG-UID5050 JASAG-UID5050 - ACS ACR122U NFC Reader Writer + 5 PCS Ntag213 NFC Tag + Free Software --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/412225925-jasag-100pcs-premium-rewritable-uid-smart-card-mi-fare-1k](https://www.desertcart.gr/products/412225925-jasag-100pcs-premium-rewritable-uid-smart-card-mi-fare-1k) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-06*
