FAQ
Which RFID card frequency should I choose?
Choose based on your reader system and application. LF, HF/NFC and UHF cards are not interchangeable unless your system supports them.
Are NFC cards 13.56MHz cards?
NFC uses 13.56MHz HF technology, but the exact chip and data format still need to match your project.
Can one card work with all RFID readers?
Usually no. The card frequency, chip and protocol must be compatible with the reader system.
Can ZealTag help identify the right frequency?
Yes. Share your reader model, existing card type or application details so ZealTag can recommend a suitable option.
