Buying Guide – How to Choose the Best Blank Rewritable Rfid Cards
Selecting the right RFID cards requires understanding your system requirements and the frequency technology your readers use.
Frequency Compatibility
The most critical factor is matching the card frequency to your reader. 125kHz and 13.56MHz are the two common standards that are not interchangeable. Always check your lock system documentation before buying to avoid incompatibility.
Always verify the frequency matches your hardware.
Chip Type and Memory
Cards come with different chips like T5577 or MIFARE. T5577 is common for simple cloning while MIFARE offers more memory and security. Choose based on whether you need basic ID or complex data storage.
Select a chip that matches your data needs.
Rewrite Capability
Some cards allow rewriting the UID while others lock it for security. Decide if you need to clone existing cards or just write new data. This determines your workflow flexibility.
Check if the UID is writable for cloning.
Pack Size and Value
Consider how many cards you need. Small packs are good for testing but bulk packs save money long term. Ensure the pack size fits your budget and deployment scale.
Buy bulk packs for large deployments.
Printer Compatibility
If you plan to print logos use cards with printable surfaces. Standard inkjet printers often fail on PVC. Look for cards compatible with UV or thermal printers for best results.
Ensure the card supports your printing method.
Physical Durability
Cards in high traffic areas should be thicker and waterproof. PVC materials with anti-scratch coatings extend life. Check thickness and resistance ratings for longevity.
Choose thicker cards for heavy use.
How to Use and Care for Your Blank Rewritable Rfid Cards
Firstly ensure you have a compatible RFID writer or copier. Most blank cards require you to program an ID before they will work with readers.
Insert the card into your writer device and follow the software instructions to copy or write a new ID. Test the card immediately after writing to ensure the data was saved correctly.
Store cards in a cool dry place away from magnets and extreme heat. Use protective sleeves to prevent scratches that might interfere with the internal antenna.
Frequently Asked Questions
Can I clone any card with these blank cards?
These cards can clone compatible frequencies. For example 125kHz cards cannot copy 13.56MHz cards. Ensure your target card matches the blank card type before attempting to clone it.
Do these work with my smartphone?
Most NFC phones work with 13.56MHz cards like MIFARE but not 125kHz ones. Check your phone capabilities and the card frequency to confirm compatibility for mobile access.
How long do these cards last?
Quality PVC cards can last years if cared for. They support up to 100000 write cycles and are resistant to water and wear making them suitable for long-term use.
Can I print logos on these cards?
Yes many cards have printable surfaces. Standard inkjets may not work well so consider UV or thermal printers for best results on PVC surfaces.
What is the difference between UID and Non-UID?
UID cards allow changing the unique ID number for cloning. Non-UID cards have a fixed ID for security. Choose UID for flexibility and Non-UID for higher security.
Do I need a license to use these?
You only need authorization to program cards for systems you legally own. Unauthorized cloning of private systems is illegal. Always follow local regulations.
