LF Card Inlay (125 kHz) Types

1 LF inlay specifications

Operating frequency 125KHz (ISO 11784/11785). Chips TK4100, EM4200, EM4305, T5577, Hitag. Substrate brand-new PVC or PET. Thickness 0.50-0.55 mm (the thicker LF antenna needs more depth than a 13.56MHz inlay). Layouts 2-5 and 5-5, standard or completely flat. Trimmed reference edges with optional cross marks.

2 Why LF inlay supply is scarce

Low-frequency antennas need many turns of copper wire to reach 125KHz, and most wire-planting machines cannot lay them cleanly, so many factories stopped making LF prelam. The kept the capability and supplies consistent LF inlay worldwide, which is why buyers with legacy EM/TK4100 programs often source LF inlay here when other suppliers only offer HF.

How Ordering Works

From inquiry to delivered lf card inlay (125 khz) in four steps

The same process every order follows — you always see a proof and approve it before anything goes to production.

  1. 1 Within 24 hours

    Send your inquiry

    Share quantity, chip and application — or send the configuration straight from the estimate above. We reply with an exact quote and a chip / format recommendation.

  2. 2 1–3 days

    Samples & artwork proof

    Free stock samples ship via DHL / FedEx so you can test read range and finish. Your artwork comes back as a print-ready PDF proof.

  3. 3 You control the clock

    Approve the proof

    Bulk production starts only after your written sign-off on the proof, chip encoding plan and numbering / UID list. Revisions before approval are free.

  4. 4 7–15 business days

    Production & delivery

    Standard lead time for stock tooling (custom molds add time — confirmed on your quote), then door-to-door express with tracking to your office or warehouse.
