Get Your Custom RFID Tags
As a leading custom RFID tag manufacturer, we craft solutions based on the unique needs of your operation. We offer a wide range of customization options, including material, size, frequency, encoding, and read distance, ensuring each RFID Tag is perfectly customized to your requirements. No matter what application you use RFID tags for, we can provide rugged, reliable RFID tags that meet the highest quality and durability standards. Here are the main ways we customize RFID tags to fit your needs.
Material Selection
Material is key for customizing RFID tags. Plastic works in harsh conditions, while softer materials suit delicate spaces. Different materials also affect signal performance. Pick what fits your use case to ensure your tags last and work reliably.
Customized Size
Size shapes usability. Small tags fit tight spaces or tiny items, while larger tags are easily read. In crowded areas, sleek tags prevent clashes. Align shape and dimension with your goods for visibility, convenience, and performance.
Frequency Requirements
Choose LF, HF, or UHF based on read range, speed, and interference. LF and HF resist metals and liquids but have shorter ranges. UHF offers an extended range yet may face signal blocks. Match frequency to your environment for reliable performance.
Reading Distance
Define the distance at which you have to read the tag. Short distances work for retail checkouts, while warehouses may need meters of coverage. Antenna design, reader settings, and power outputs affect range.Adjust these factors to capture data accurately at the distance you need.
Encode
Plan how data is stored on each tag. Some only hold an ID, while others contain detailed info. Decide if you need a simple EPC or added user memory. Ensure your chosen format works with existing software. Proper encoding streamlines processes and slashes errors.
Application Environment
Consider real-world conditions. Temperature swings, humidity, and chemicals can degrade tags. For outdoor use, opt for UV-resistant casings. In healthcare or food settings, ensure compliance with safety rules. Matching your tags to the environment maximizes their lifespan.
