RFID cards arent all the same, learn from my mistakes.. ### ⭐ these cards are NOT 0 block rewritable *by M***N on August 22, 2024* Even though it says in the title, when tried, a writer is only able to access 63 of 64 blocks, meaning it's NOT 0 block rewritable. For some uses, these will work, but I HIGHLY recommend to find some other cards. They just lied here. ## Frequently Bought Together - LEXI 20pcs Rewritable UID Smart Card, 13.56MHz Changeable RFID PVC Blank Card for 1K S50 MF1 Mi-fare Door Access Control, Block 0 Sector - ACS ACR122U NFC Reader Writer + 5 PCS Ntag213 NFC Tag + Free Software - LEXI 100pcs Mi-Fare 1K S50 RFID Card, Rewritable UID Smart Card, Premium 13.56MHz PVC Blank Card for Door Access Control, Block 0 Sector --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/223120931-lexi-20pcs-rewritable-uid-smart-card-13-56mhz-changeable-rfid](https://www.desertcart.hr/products/223120931-lexi-20pcs-rewritable-uid-smart-card-13-56mhz-changeable-rfid) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
