DescriptionSecure your facilities, streamline your attendance tracking, and issue professional identification with the 13.56MHz MIFARE 1K PVC Smart Card. Widely recognized as the global standard for contactless security solutions, this blank smart card combines robust digital encryption with a highly customizable exterior.Whether you are an IT administrator deploying a cashless payment system, or prepping hardware kits for an upcoming IoT summer training program, these MIFARE 1K cards provide fast, reliable, and secure data transmission.RFID vs. NFC: Which is this card?It is important to know exactly what technology you are buying for your project. This MIFARE 1K card operates as a High-Frequency (HF) RFID card. While it operates on the 13.56MHz frequency (the same frequency used by NFC), it utilizes a proprietary NXP encryption protocol. This makes it incredibly secure for access control systems and perfect for reading via an Arduino or ESP32 using the standard RC522 RFID module. Note: Because it uses proprietary encryption, it is not universally NFC Forum compliant. If you are looking for a card specifically to share website URLs or digital business cards with smartphones, you should look for an NTAG series card (like the NTAG213 or NTAG215).Fully Printable & Custom-ReadyThese cards are manufactured to the standard CR80 size (the exact dimensions of a standard credit card) using premium, waterproof Polyvinyl Chloride (PVC). Both sides feature a clean, glossy white finish designed to absorb ink from professional dye-sublimation ID card printers (such as Zebra, Fargo, Magicard, and Evolis). You can easily print company logos, student photos, barcodes, and custom text directly onto the card surface.1KB of Secure MemoryOperating under the ISO 14443A protocol, these cards feature an internal EEPROM memory of 1024 bytes (1KB). This memory is intelligently organized into 16 sectors, each protected by two different security keys. This allows you to use a single card for multiple secure applications simultaneously—for example, Sector 1 could handle lab door access, while Sector 2 manages a cafeteria cashless payment system!Key Features:Fast Contactless Reading: Operates seamlessly with standard 13.56MHz RFID readers at a distance of up to 10cm.High Security: Features mutual three-pass authentication and data encryption to prevent cloning and unauthorized reading.Durable Construction: Waterproof, dustproof, and resistant to everyday wear and tear.Rewritable: Data can be written and erased over 100,000 times, with a data retention span of up to 10 years.Technical Specifications:Technology: High-Frequency (HF) RFIDOperating Frequency: 13.56 MHzRF Protocol: ISO/IEC 14443 Type AMemory Capacity: 1K Byte (1024 Bytes) EEPROMReading Distance: 2.5cm to 10cm (Depending on the reader module and antenna)Read/Write Time: ~1 to 2 millisecondsDimensions: 85.6mm x 54mm x 0.84mm (Standard CR80 Credit Card Size)Material: PVC (Glossy White, Printable)Ideal Applications:Secure door access control and smart locksEmployee ID badges and time/attendance trackingUniversity student identification and library systemsEvent ticketing and VIP passesMicrocontroller security prototypes (using ESP32/Arduino with MFRC522 modules)
