Chip model: The more popular NFC chip models are NTAG213, NTAG215, NTAG216, ou MIFARE series. Different chip models determine different characteristics such as read/write distance e storage space (common storage capacities include 144 bytes, 504 bytes). So, you can choose the right chip model according to your needs~
Each chip’s storage capacity and reading performance differ. For example:
NTAG213: Commonly used, good stability, suitable for most scenarios.
NTAG216: Larger capacity (888 bytes), ideal for storing more information.
If you just need it for access control or simple information recording, 144 bytes of capacity is sufficient. But if you want to store URLs, QR codes, business cards, and other content, it’s recommended to choose a model with larger capacity.
Frequência de trabalho: NFC epoxy tags operate at 13,56 MHz, which is compatible with most NFC reading software and various mobile phone models.
Material selection: Common materials include PVC, BICHO DE ESTIMAÇÃO, abdômen, etc.
PVC is waterproof, wear-resistant, and flexible, making it suitable for outdoor use.
BICHO DE ESTIMAÇÃO features high transparency, heat resistance, tear resistance, and chemical corrosion resistance.
Glue dripping process: High-quality manufacturers ensure that the glue is evenly applied, bubble-free, and free of impurities. Such NFC epoxy tags are not only beautiful but also durable.
The shell of the NFC epoxy tag not only affects the appearance but also determines its longevity. Common materials can be processed with glue to make them waterproof, dustproof, and scratch-resistant.
The transparent “crystal glue” on the surface not only protects the chip but also adds texture and gloss to the tag — especially suitable for personal accessories ou corporate promotions.
Tamanho: The most popular sizes are 25mm e 30 mm. In addition, we support custom sizes, and you can contact us to request free samples based on your needs.
Shape: Round, square, or custom-shaped — the choice is yours! As long as it can be attached and used effectively.
For example:
If you want to attach it to a keychain ou phone case, a smaller size is more convenient.
For display use, restaurant menus, table cards, etc., a larger 70mm tag is more suitable.
NFC epoxy tags can be personalized based on various application needs, such as:
Impressão QR codes, barcodes, serial numbers;
Supporting laser UID numbering, inkjet printing, and more — very useful for identity recognition e anti-counterfeiting tracking.
