FAQ

Frequently Asked Question.

Can RFID tags be pre-programmed before shipment?

Yes.

To help simplify your production or deployment process, we can pre-encode RFID tags before shipment.

Programming services include:

  • UID recording
  • EPC encoding
  • User memory writing
  • URL encoding
  • Product ID programming
  • Asset numbers
  • Sequential serial numbers
  • Password protection
  • Data verification

Every programmed tag can be verified before delivery to ensure accuracy and consistency.

Can every RFID tag have a unique ID?

Yes.

Each RFID tag contains a factory-programmed unique identifier (UID or TID), and we can also assign customized unique numbers according to your project requirements.

We support:

  • Sequential numbering
  • Random numbering
  • Asset IDs
  • Employee IDs
  • Product serial numbers
  • EPC coding
  • QR codes matching RFID data

This is especially useful for inventory management, product traceability, anti-counterfeiting, and asset tracking applications.


Do you supply RFID readers and antennas?

Yes.

In addition to RFID tags, we also supply RFID hardware solutions, including:

  • USB Desktop Readers
  • Fixed RFID Readers
  • Handheld RFID Readers
  • Embedded RFID Modules
  • UHF RFID Readers
  • HF RFID Readers
  • Multi-port RFID Readers
  • Circular Polarized Antennas
  • Linear Polarized Antennas

Our readers are compatible with Windows, Android, Linux, and other operating systems. SDKs and technical documentation are available to support system integration.

Which RFID tag is best for my application?

The ideal RFID tag depends on your application environment, reading distance, mounting surface, and operating conditions.

Here are some general recommendations:

  • Retail inventory → UHF RFID Labels
  • Warehouse management → Long-range UHF RFID Tags
  • Asset tracking → ABS or Anti-Metal RFID Tags
  • Access control → RFID Cards or Keyfobs
  • Library management → HF RFID Labels
  • Laundry management → Washable RFID Laundry Tags
  • Livestock management → RFID Ear Tags
  • Tool tracking → Industrial Anti-Metal RFID Tags

If you are unsure which product to choose, simply tell us your application, and our engineers will recommend the most suitable RFID solution.

Can you manufacture products according to our drawings or samples?

Absolutely.

We can manufacture RFID products based on your technical drawings, design files, physical samples, or project specifications.

Our engineering team will evaluate your requirements and provide recommendations to optimize product performance, manufacturability, and cost.

What file formats do you accept for artwork?

For the best printing quality, we recommend providing vector artwork.

Accepted file formats include:

  • AI
  • EPS
  • PDF
  • CDR

High-resolution PNG or JPG files may also be accepted for simple designs.

If you do not have professional artwork, our design team can help prepare production-ready files.

Can I order samples before placing a bulk order?

Yes.

We highly recommend ordering samples before mass production, especially for customized projects.

Sample orders allow you to evaluate:

  • Product quality
  • Reading performance
  • Material
  • Printing quality
  • Compatibility with your RFID system

After sample approval, we proceed with mass production according to the confirmed specifications.

How long is the production lead time?

Production time varies depending on the product type, order quantity, and customization requirements.

Typical lead times are:

  • Standard samples: 3–5 working days
  • Customized samples: 5–7 working days
  • Standard bulk orders: 7–12 working days
  • Customized bulk orders: 10–20 working days

For urgent orders, we will do our best to arrange priority production whenever possible.
