MIFARE Classic 1K (S50) 13.56MHz Blank RFID Printable Card
Product Overview
The MIFARE Classic 1K (S50) 13.56MHz Blank RFID Printable Card is a high-frequency contactless smart card designed for secure identification, access control, and data storage applications. Built around the industry-standard NXP MIFARE Classic 1K chip, this blank PVC card operates at 13.56 MHz and complies with the ISO/IEC 14443-A communication protocol. It provides 1024 bytes of user memory organized into 16 sectors with 4 blocks each, offering sufficient storage for credentials, loyalty points, transit fare balances, or personal identification data. System integrators, access control contractors, public transit operators, and facility managers deploy this card in large-scale projects where reliable read performance, data security via CRYPTO1 encryption, and compatibility with existing HF RFID infrastructure are required. As a blank printable card, it supports dye-sublimation and thermal transfer printing, allowing organizations to customize card surfaces with logos, photos, barcodes, and branding before issuance.
Product Advantages
Procurement teams and project buyers choose this MIFARE Classic 1K card because it balances cost efficiency with proven field performance across thousands of deployed access control and transit systems worldwide. The 13.56 MHz operating frequency enables read distances up to 10 cm with standard antenna configurations, making it practical for physical access points such as turnstiles, door readers, and parking barriers. The 106 kbps data transfer rate ensures fast card authentication, reducing wait times at entry points or fare validation stations. For system integrators and distributors managing large deployments, the card’s factory-default authentication keys (FF FF FF FF FF FF) simplify initial programming while allowing custom key configuration for enhanced security per project requirements. The CRYPTO1 encryption layer protects data transmission between the card and reader, preventing unauthorized cloning or tampering—a critical requirement for commercial access control and payment applications. Commercial buyers benefit from the card’s batch-to-batch consistency, ensuring that each unit in a bulk order performs identically, which simplifies programming workflows and reduces field failures.
