Buying Guide – How to Choose the Best Blank Rewritable Rfid Cards
Selecting the right blank rewritable Rfid card involves understanding your specific access control needs and technical compatibility requirements.
Frequency Compatibility
Ensure the card frequency matches your readers. Common types are 125kHz for proximity and 13.56MHz for smart Mifare or NFC systems.
Always verify your device specs before buying to avoid incompatibility issues.
Rewritability
Check if the card allows writing to Block 0 (UID) or if it is locked. Rewritable UID cards offer more flexibility for cloning and customization.
Locked UID cards are more secure but cannot be modified for duplicate IDs.
Memory Size
Different chips offer varying memory capacities. Standard Mifare Classic 1K cards have 1024 bytes while NTAG cards may have less but offer better security.
Choose based on how much data you need to store on each card.
Durability
Look for PVC material that is waterproof and scratch-resistant. Thickness can also affect longevity in high-traffic environments.
Thicker cards often withstand daily handling better than thin ones.
Pack Size
Buy in bulk if you need replacements for large teams. Smaller packs are better for testing or personal projects.
Consider the cost per card when choosing bulk options.
Printer Compatibility
If you need to print custom logos, ensure the card surface supports thermal sublimation or UV printing.
Matte surfaces generally work better for custom branding than glossy ones.
How to Use and Care for Your Blank Rewritable Rfid Cards
First, verify your RFID reader or writer supports the card frequency and protocol. Use the appropriate software like RFID Tool or specific copier utilities to program the data.
Second, program the card by placing it close to the writer and initiating the write process. Ensure the data matches the access credentials required by your system.
Third, keep cards away from extreme heat, water, or magnetic fields to preserve data integrity. Clean them with a soft cloth to avoid scratching the surface.
Frequently Asked Questions
Can I use these cards on any NFC phone?
Not all cards work with NFC phones. Only 13.56MHz NFC-compatible cards like NTAG can be read by phones. Proximity cards at 125kHz will not work with mobile NFC.
What is the difference between 125kHz and 13.56MHz?
125kHz is a low frequency used for basic proximity access like hotel keys. 13.56MHz is a higher frequency used for smart cards with more data storage and security features.
Can I rewrite these cards unlimited times?
Most rewritable cards support up to 100,000 write cycles. While this is high, it is not unlimited. Excessive rewriting over years may eventually reduce lifespan.
Do I need special tools to use these cards?
Yes, you need a compatible RFID writer or copier to program blank cards. Without these tools, the cards will remain blank and unreadable by your access system.
Are these cards secure for office use?
Rewritable cards can be less secure than locked UID cards. For high-security areas, consider using cards with locked Block 0 or encryption features.
Can I print on these cards?
Many models support printing. Ensure the card surface is compatible with your printer type, such as thermal sublimation or UV for custom branding.
