Product Description

RFID Key Fob - Durable Access Control Solution for Enterprise Security

With dual-frequency choices of 125kHz and 13.56MHz and advanced encryption technology, our RFID key fob offers enterprise-grade performance. WS-RFID Technology makes each key fob with quality ABS or silicone encapsulation, which makes them very durable with a failure rate of less than 0.1%. With read ranges of up to 15 cm, data retention of 10 years or more, and over 100,000 write cycles, our key fobs work with hotel entry, workplace attendance, and smart building systems without any problems. We have been making high-quality products for 15 years and can make more than 500 million units a year. We can send regular orders in just 7–10 days.

What Makes Our RFID Key Fob Stand Out?

Built for Heavy-Duty Use

Your input passwords must be strong enough for daily usage. The impact-resistant casings of our key fobs can withstand drops, scratches, and severe handling. Your personnel won't lose them because they're compact and attachable to purses, belts, and lanyards.

These key fobs function in parking lots, cold storage facilities, and heated industries from -25°C to +70°C.

Advanced Chip Technology

We have common chip choices, such as:

  • Industry-standard protection from the NXP Mifare line
  • The Desfire line offers high-tech security for private places.
  • The Ntag line has a lot of different NFC uses.
  • The EM4100 is a cheap entry control system.
  • Fudan and Huada Electronics are great options for people in China.

Because of this, the chip can be changed to fit your price and protection needs.

Seamless System Integration

With the system that is already in place, your product functions. We support both ISO/IEC 14443 and EM4100 protocols, which means that they will work with most access control readers around the world. Our key fobs work well with existing systems, so you don't have to spend a lot of money on system overhauls when you want to improve hotel locks or increase company security.

Where You Can Use RFID Key Fobs?

Corporate Environments

Control how employees can get into limited areas, computer rooms, or R&D labs. Stop checking people in by hand and use digital attendance tracking instead.

Residential Communities

Make it safe and easy for people to get into buildings, gates, and services. Registering guests and giving them temporary key fobs will make things safer.

Hospitality Industry

Replace hotel room keys with key fobs that are sturdy and can be programmed again and again. Lessen the cost of replacing and make the guest experience better.

Parking & Transportation

Automatically let vehicles in and out. Assign parking spots to specific people and easily keep track of how they're being used.

Educational Institutions

With a single pass, you can control who can enter the dorms, the library, and other school buildings.

Industrial & Government Facilities

Use encrypted access control to keep private areas like work zones, vaults, or classified document rooms safe.

FAQ

Q: What's the difference between 125kHz and 13.56MHz key fobs?

A: 125kHz (LF) key fobs work well for basic access control and are cost-effective. 13.56MHz (HF) key fobs offer faster data transfer, better security encryption, and support NFC applications like mobile integration.

Q: Can I reprogram key fobs for different users?

A: Yes. Key fobs with read/write chips support reprogramming over 100,000 cycles. Read-only chips are programmed once during manufacturing.

Q: How do I ensure key fobs work with my current system?

A: Share your access control reader specifications with us. We'll recommend compatible chip models and protocols. Free samples let you test before ordering.

Q: What's your minimum order quantity?

A: We accommodate both small trial orders and large-volume deployments. Contact our team for specific MOQ details based on customization requirements.

Q: Do you offer technical support for system integration?

A: Absolutely. Our engineers provide SDK documentation, integration guidance, and ongoing technical support to ensure smooth deployment.

Q: How durable are these key fobs in outdoor environments?

A: Very durable. With an operating range of -25°C to +70°C and impact-resistant encapsulation, our key fobs perform reliably in parking lots, gates, and outdoor access points.
