RFID Key Fob Tag

RFID Keyfob Tag

This is a high-frequency passive tag working at high frequency, built around the NXP NTAG213 chip, 13.56 MHz, compliant with ISO14443A.

Chip & RF Performance

The NTAG213 is part of NXP's NFC family. It offers 144 bytes of user memory that can be freely read and written, with more than 100,000 erase/write cycles. Typical read range is 2–5 cm - about twice that of an EM4100 tag of the same size - and it holds up better when used near metal. Works with almost any standard 13.56 MHz reader on the market; you can talk to it using normal RFID commands, so it drops straight into existing systems or your own apps.

Physical Specs

Size: 37 × 31 × 5.5 mm (custom sizes available)

Weight: ~5 g each

Operating temperature: –20 °C to +70 °C

Housing is made of engineering-grade ABS, injection-molded in a metal tool in one shot. The chip is a copper-coil COB module, everything ultrasonically welded shut. There's a hole at the top for a lanyard, strap or key ring.

Tags have passed soak, drop, and acid/alkali exposure tests with no loss of function. Color doesn't fade, shell doesn't warp or peel even after years.

Surface Finishing (for bulk orders)

• Inkjet numbering (serial or batch numbers)
• Laser engraving (permanent)
• Silk-screen printing (logo, text, QR code)

Stock colors: black, red, yellow, blue, green. Other colors require new tooling or custom color matching.

Common Uses

Access control & attendance

One tag can handle building entry, office clock-in, gym membership, library cards, etc.

Micropayments

Write wallet data to the tag → tap at POS to pay. Check balance or top up via phone app or kiosk.

Asset tracking

144 bytes is plenty for an equipment ID or short note; makes stock-taking quick with a handheld reader.

Packing & Shipping

Inner bag: 100 pcs in resealable OPP bag

Outer carton: 2,000 pcs in corrugated box, 38 ×20 ×28 cm, approx. 12 kg gross

Large orders can be repacked or palletized to meet destination port requirements.

Order Process

Send us model, quantity, color, and any printing content → we quote → you confirm and pay → production starts → three full inspections before shipping → tracking number sent once it ships → delivered and signed for.

Quick RFID

Primer RFID = Radio Frequency Identification. Data is exchanged wirelessly between reader and tag without contact. 13.56 MHz is the high-frequency band - perfect for short-range, accurate identification. That's why you see it everywhere in payments, access control, logistics, etc.
