Its standout feature is the unlocked Block 0 Sector, which allows the UID to be changed. This is crucial for cloning legitimate access cards for personal or authorized business use. The card supports over 100,000 rewrite times, ensuring longevity even with frequent updates. The PVC construction is durable and fits standard card sleeves perfectly.

While the card is versatile, it requires a writer capable of handling MIFARE Classic 1K chips. Some users may find the setup process technical if they are new to RFID cloning. Additionally, the 1K memory limit restricts advanced data storage compared to larger memory cards. These trade-offs are acceptable for standard access control needs.

This product is ideal for technicians, small business owners, or hobbyists who need reliable rewritable cards. If your system relies on 13.56MHz MIFARE protocols, this card offers the right balance of performance and affordability. We recommend it for users seeking a dependable tool for cloning and customization tasks.

Unlockable UID for Cloning

The ability to rewrite the Unique ID in Sector 0 makes these cards essential for duplicating access credentials securely.

High Rewrite Durability

With over 100,000 rewrite cycles, these cards are built to withstand frequent reprogramming in high-use environments.

We may earn a commission when you buy through this link, at no additional cost to you.

These cards are particularly strong for event admissions and temporary visitor authorization. The EV1 chip allows for up to 100,000 write cycles and ten-year data retention. Users can lock specific pages to prevent unauthorized changes, ensuring data integrity over time. The waterproof and scratch-resistant PVC material ensures durability in busy environments.

However, these cards come factory locked and require an unlock command via NFC Tools before full use. This extra step might confuse beginners expecting plug-and-play functionality. Additionally, the 48-byte memory is quite limited compared to MIFARE 1K cards. For simple links or IDs, this is sufficient, but complex data needs may require a different chip.

Ideal for event organizers or businesses creating branded NFC badges, these cards provide a professional look. The ability to print directly on the surface using thermal printers adds significant value. If you need secure, customizable NFC tags for short-term use, this pack is a solid investment.

Secure Data Protection

Built-in features like OTP and configurable passwords protect stored information from unauthorized access or tampering.

Custom Printing Ready

Buying Guide – How to Choose the Best Blank Rewritable Rfid Cards

Selecting the right blank rewritable RFID card requires understanding frequency, chip type, and system requirements. This guide outlines the key factors to consider to ensure compatibility and performance.

Frequency Compatibility

The most critical factor is matching the card frequency to your reader. High-frequency 13.56MHz cards work with modern MIFARE systems and smartphones. Low-frequency 125kHz cards are used in older door locks and parking systems. Using the wrong frequency renders the card useless.

Always verify your system's frequency before buying. If your reader supports NFC, opt for 13.56MHz. For standard proximity locks, 125kHz is likely your choice.

Chip Type and Security

Different chips offer varying security and storage. T5577 chips are simple and easy to clone. MIFARE Classic 1K cards have sector-based memory for keys. NTAG chips offer advanced security features like OTP. Choose based on whether you need simple access or data security.

For basic access cloning, T5577 is sufficient. For secure enterprise use, MIFARE with locked blocks is safer.

Rewrite Limits

Rewritable cards have a maximum number of write cycles. Most standard cards support 100,000 writes. This ensures they last years of daily use. If you need frequent data changes, confirm the cycle limit.

Standard 100,000 cycle cards are durable enough for most business and personal uses.

Memory Capacity

Memory size affects how much data you can store. NTAG Ultralight has 48 bytes. MIFARE 1K has 1024 bytes. Choose based on whether you store a simple ID or complex data like tickets.

For simple access IDs, minimal memory is fine. For event tickets or payment, larger memory is required.

Printer Compatibility

If you need logos, check if the card is printable. Thermal and UV printers work on PVC surfaces. Ordinary inkjet printers usually cannot print on these cards directly. Uncoated surfaces are best for customization.

Use thermal or UV printers for professional branding. Standard inkjet will not work on most PVC RFID cards.

Pack Size and Cost

Bulk packs reduce the cost per card significantly. Buying 100 cards is cheaper per unit than 10. However, ensure you have storage space. Small packs are better for testing.

Buy bulk for office needs. Start small if you are unsure of system compatibility.

Physical Durability

Thickness and material matter for long-term use. Standard cards are 0.8mm. Thick cards are 1.8mm and resist bending. Waterproof PVC ensures longevity in humid or busy environments.

Choose thicker cards for industrial use. Standard cards work well for office badges.

Locking Mechanisms

Some cards have locked sectors that cannot be written. This prevents data loss but limits cloning. Check if Block 0 is unlockable if you need to clone UIDs.

Unlockable Block 0 is needed for UID cloning. Locked Block 0 is better for secure IDs.

How to Use and Care for Your Blank Rewritable Rfid Cards

To program your cards, you need a compatible RFID writer or copier. Connect the writer to your computer or power it on. Place the blank card on the writer pad and select the write mode. Enter the ID or data you wish to program. Wait for the confirmation light before removing the card.

Care for your cards by avoiding extreme heat or direct sunlight. Keep them away from water if they are not waterproof rated. Do not bend the cards sharply as this can damage the internal antenna. Store them in a protective box or sleeve when not in use.

Regularly clean the surface with a soft dry cloth to remove dust. If you print on the cards, allow the ink to dry completely before use. Avoid using harsh chemicals on the surface. Proper care extends the life of the chip and ensures reliable reads.
