Product Overview
The MIFARE Classic EV1 1K (S50) 13.56MHz Blank RFID Printable Card is a high-frequency contactless smart card built around the original NXP MIFARE Classic EV1 1K chip (MF1S50). Designed for secure identification, access control, and data storage applications, this card operates at 13.56 MHz and complies with the ISO/IEC 14443-A communication standard. System integrators, facility managers, and access control contractors choose this card for its proven compatibility with existing reader infrastructure, including the ACR122U and other standard NFC-enabled devices. As a wholesale RFID card supplier, do rfid reader manufacturer stocks this card in bulk to support large-scale deployments in commercial buildings, transit systems, and enterprise identification programs.
Product Advantages
Proven Chip Architecture for Reliable Access Control
The original NXP MIFARE Classic EV1 1K chip delivers consistent read/write performance across thousands of daily transactions. With 1024 bytes of user memory organized into 16 sectors of 4 blocks each, the card supports sector-based data segmentation, making it suitable for multi-application scenarios such as combining access credentials with cashless payment or time attendance data on a single card. The 4-byte UID ensures straightforward integration with most access control and time tracking systems currently deployed in commercial facilities.
CRYPTO1 Encryption for Secure Data Transmission
Each transaction between the card and reader is protected by CRYPTO1 encryption, preventing unauthorized reading or cloning of stored data. This level of security meets the operational requirements of corporate office buildings, co-working spaces, and gated communities where credential integrity must be maintained without adding authentication latency at entry points.
Broad Reader Compatibility Reduces Deployment Risk
The card communicates at up to 106 kbps over a read range of up to 10 cm using the ISO/IEC 14443-A protocol. This standardized interface ensures the card works with the majority of 13.56 MHz readers already installed in the field. Project managers can deploy these cards without replacing existing reader hardware, reducing per-site integration costs and accelerating rollout timelines.
Printable PVC Surface for Custom Branding and Badging
The 0.8 mm thick PVC card body accepts dye-sublimation and thermal transfer printing, allowing organizations to print employee photos, company logos, membership numbers, or visitor credentials directly onto the card. This eliminates the need for adhesive labels or separate ID badges, consolidating identification and access control into a single durable credential.

Industrial Applications
Access Control for Commercial Buildings
Facility managers and security contractors deploy this card as a primary credential for employee entry, visitor access, and restricted area management. The 1K memory capacity allows encoding of multiple access zones on a single card, reducing the number of credentials an employee must carry. System integrators appreciate the plug-and-play compatibility with existing 13.56 MHz readers, which avoids additional hardware procurement during system upgrades.
Public Transportation Ticketing
Transit authorities and fare collection system operators use MIFARE Classic EV1 1K cards for stored-value ticketing and pass validation. The 16-sector memory structure enables separation of fare balance, journey history, and rider identification data within a single card, simplifying back-end database management. The fast data transfer rate of 106 kbps supports quick tap-and-go transactions at turnstiles and validators during peak commute hours.
Loyalty and Membership Programs
Retail chains, fitness centers, and hospitality venues issue these cards as membership credentials with embedded loyalty points or prepaid balances. The printable surface allows each card to carry the member’s name and program branding, improving user engagement and reducing card misuse. Wholesale purchasing from do rfid reader manufacturer ensures consistent card quality across multiple locations.
Cashless Payment Systems
Cafeterias, vending machine operators, and corporate canteens implement prepaid payment using this card. The CRYPTO1 encryption protects stored value data during read and write operations, meeting the security requirements of closed-loop payment environments. Bulk ordering from the factory supports rapid deployment across dozens or hundreds of point-of-sale locations.
Identification and Employee Badging
HR departments and security officers print employee photos and credentials directly onto the card using standard PVC card printers. Combining visual identification with RFID access control on a single card reduces administrative overhead and eliminates the need for separate badge holders. The durable PVC material withstands daily wear, extending credential replacement cycles.
OEM / ODM Manufacturing Support
do rfid reader manufacturer provides OEM and ODM customization for the MIFARE Classic EV1 1K card to meet specific project requirements. Customization options include printing company logos, encoding custom sector keys, programming unique UID ranges, and selecting alternative card sizes or materials. OEM partners receive pre-programmed cards with sector keys aligned to their access control software, reducing field configuration time during deployment. ODM clients can request custom packaging, barcode labeling, and documentation for distribution to end users. The factory supports small-batch pilot runs and full-scale production orders with consistent encoding accuracy across the entire lot.
Factory Production Advantages
As a dedicated RFID card manufacturer, do rfid reader manufacturer operates a production facility capable of processing high-volume card orders while maintaining batch-to-batch consistency. The production line handles the full cycle from PVC sheet cutting to chip embedding, antenna lamination, and final quality inspection. Each card is tested for read range, memory functionality, and communication protocol compliance before packing. This in-house production control means lead times remain predictable even during peak demand periods. The factory’s experience with export logistics supports timely delivery to distributors and project sites worldwide. For system integrators and wholesale buyers, this stable production capacity reduces the risk of supply interruptions during multi-year access control projects.
