Introduction
Choosing the right NFC chip is one of the most important steps when sourcing RFID wristbands. Different chip models such as NTAG213, NTAG216, Ultralight, and DESFire come with varying storage capacities, security levels, and compatibility with mobile devices. This guide will explain the key factors to consider, compare popular NFC chips, and help you decide which one fits your project best.
Key Factors to Consider
When selecting an NFC chip for wristbands, buyers should evaluate:
Memory Size
Determines how much data the chip can store (e.g., URL, ID number, text).
For simple access control, small memory chips are enough.
For interactive marketing or larger datasets, higher memory is needed.
Security Level
Basic chips (like Ultralight) offer limited protection.
Advanced chips (like DESFire) support encryption, suitable for payment or sensitive data.
Compatibility
Ensure the chip works with both Android and iOS devices.
Some chips may not support older iPhones.
Application Scenario
Event ticketing, hotel access, hospital management, or cashless payment may require different chip levels.
