Buying Guide – How to Choose the Best Blank Rewritable Rfid Cards
Selecting the right card depends on your specific system requirements and use case. Below are key factors to consider before making a purchase.
Frequency Compatibility
RFID cards operate at different frequencies, primarily 125kHz and 13.56MHz. You must match the card frequency to your reader system. Using the wrong frequency will result in failure to read.
Always verify your system specification before buying. Low frequency cards are common for hotel keys while high frequency cards are used for Mifare systems.
Chip Type
The chip determines functionality and security. Common types include T5577 for 125kHz and Mifare Classic or NTAG for 13.56MHz. Some chips support cloning while others offer advanced encryption.
Choose a chip that matches your programming needs. Basic proximity use requires T5577 while secure access needs Mifare or EV1 chips.
Rewrite Cycles
Rewrite cycles indicate how many times you can change data on the card. Most high-quality cards offer over 100000 writes. This is critical for frequently updated access permissions.
Check the rated cycle count for longevity. Higher numbers ensure the card remains functional after repeated updates.
Material Durability
Cards are typically made of PVC. Look for waterproof and scratch-resistant features for daily use. Thicker cards like 0.8mm are durable for badge sleeves.
Premium options may offer better resistance to bending or yellowing. Durability is important for long-term commercial use.
Printability
If you need logos or text, check if the card supports printing. Some cards work with thermal or UV printers while others do not support inkjet printers.
Matte surfaces often provide better print results. Ensure the card matches your printer capabilities for customization.
Security Features
Advanced security like OTP and lock bits prevents unauthorized changes. Cards like NTAG EV1 offer configurable password protection. Standard cards may have simpler security.
Consider how secure your application needs to be. Higher security ensures data integrity and prevents cloning.
Read Range
Read range determines how close the card must be to the reader. Most cards range from 0 to 10cm. Longer ranges are beneficial for certain applications.
Ensure the range fits your physical setup. Closer ranges are standard for secure entry points.
Pack Quantity
Card packs range from 5 to 100 units. Bulk packs offer better value for organizations. Individual packs are suitable for testing.
Buy in bulk to save cost. Consider future needs when selecting pack size.
How to Use and Care for Your Blank Rewritable Rfid Cards
First, confirm your system frequency and chip type. Use a compatible RFID writer to program your ID data onto the blank card. Ensure the writer is set to the correct protocol like T5577 or Mifare.
Second, test the card on your reader after programming. Verify that the access control or event system recognizes the new ID. If issues occur, check the writer settings and card placement.
Third, handle cards with care to avoid bending or scratching the chip area. Store them in a protective sleeve or box when not in use. Keep them away from extreme heat or magnets to maintain functionality.
Frequently Asked Questions
Can I program these cards with a smartphone?
Most T5577 and Mifare Classic cards cannot be programmed directly by standard smartphones. You typically need a dedicated USB reader or specialized hardware to write data. NFC phones can read some high-frequency cards but writing requires specific apps or tools.
Do these cards work with my hotel lock?
Only if the lock uses a compatible 125kHz or 13.56MHz frequency. Check your current key specification before purchase. Many hotel systems use proprietary encryption which standard blank cards cannot bypass.
How many times can I rewrite the data?
Most high-quality cards support over 100000 rewrite cycles. This ensures longevity for repeated updates. Check the specific product specifications for the exact limit.
Are these cards safe for daily use?
Yes, PVC cards are durable and waterproof. They resist water and minor scratches effectively. Avoid bending or exposing to extreme heat to extend their lifespan.
What is the difference between T5577 and EM4100?
T5577 chips are rewritable while EM4100 chips are read-only. T5577 allows you to program custom IDs. EM4100 has a fixed ID printed during manufacturing.
Do I need special software to write to these cards?
Yes, you need an RFID writer tool and compatible software. Tools like Proxmark3 or ACR122U work well. Follow the device instructions to write the data correctly.
