Frequently Asked Questions
What is an RFID Keyfob?
RFID Keyfob is a mini contactless RFID tag with integrated key ring. The chip and antenna are sealed inside ABS housing. It is portable, waterproof and rugged, designed to carry together with keys. It is an alternative to RFID PVC cards and clamshell cards.
What is the difference between RFID keyfob, PVC card and clamshell card?
RFID Keyfob: Small keychain form, easy to carry on keys, waterproof sealed shell, not printable by ID card printers. RFID PVC Card: Standard CR80 thin laminated card, printable with photo/logo, for ID badge use. RFID Clamshell Card: Thick 1.8mm ABS card with hanging slot, heavy-duty for industrial access.
Can you supply both 125KHz and 13.56MHz NFC keyfobs?
Yes. LF 125KHz (TK4100 / EM4100 / T5577) works for traditional proximity access readers. HF 13.56MHz Mifare / NTAG versions support NFC mobile phone reading and encrypted access systems. Confirm your reader frequency before ordering.
Can we print our logo or engrave serial numbers on keyfobs?
Yes. We support silk-screen printing logos and laser engraving unique UID numbers on the ABS surface.
Can you pre-program chips and provide UID Excel list?
Yes. We can encode UID, write sector data for Mifare chips, program rewritable T5577 keyfobs, and export sequential ID list for your access software registration.
Are RFID keyfobs waterproof?
Yes, ultrasonic sealed construction is IP65 waterproof, suitable for daily outdoor use, rain and splashing. Do not leave it submerged in water for long periods.
Is T5577 keyfob able to copy existing ID cards?
T5577 is rewritable, compatible with most 125KHz ID duplicators. Please note local regulations on duplication; test samples first with your duplicator.
Will the key ring fall off easily?
The metal split ring is installed firmly on the molded hole of the ABS shell. Normal daily pulling will not break it.
What is the MOQ for custom colour and logo keyfobs?
Blank stock keyfobs support small orders with fast lead time. Custom colour shells and printed logo orders have separate MOQ based on artwork.
Can I get samples for testing?
We provide blank keyfob samples for reader compatibility test and quality check before bulk order.
