What's the difference between Type 2 Type 4 and Type 5 tags ?

NFC tags come in several types each with different capabilities memory sizes and compatibility. Here's a breakdown of the main differences between Type 2 Type 4 and Type 5 NFC tags:

Type 2 NFC Tags
Example Chip: NTAG213
Technology: Based on ISO/IEC 14443-A.
Memory Size: Typically between 48 bytes and 2 KB.
Read/Write Speed: Slower compared to Type 4 tags with a data rate up to 106 kbps.
Re-writable: Yes can be locked to read-only if needed.
Typical Use: Basic applications like storing URLs contact information and other small data.
Power Requirements: Passive doesn't require a battery.
Price: Generally inexpensive making them suitable for simple use cases.

Type 4 NFC Tags
Example Chip: NTAG424
Technology: Based on ISO/IEC 14443-A or 14443-B.
Memory Size: Can hold larger data typically up to 32 KB.
Read/Write Speed: Faster with speeds up to 424 kbps.
Re-writable: Yes but can be permanently locked to read-only if needed.
Typical Use: More complex applications like secure payments ticketing and ID cards.
Advanced Features: Support for encryption and authentication, making them suitable for secure applications.
Power Requirements: Passive.
Price: Usually more expensive than Type 2 tags due to enhanced capabilities.

Type 5 NFC Tags
Example Chip: ICODE SLIX
Technology: Based on ISO/IEC 15693.
Memory Size: Typically between 64 bytes to 8 KB.
Read/Write Speed: Typically lower than Type 4 tags, but with extended range (up to 1 meter in some cases).
Re-writable: Yes, can be locked if needed.
Typical Use: Applications that require long-range readability, such as access control and inventory tracking.
Range: Designed for longer read ranges (up to 1 meter), which is unique among NFC tags.
Power Requirements: Passive.
Price: Varies, generally moderate to high depending on the range and storage capacity.

Summary
Type 2: Basic, small storage, low cost, short range, suitable for simple uses.
Type 4: High storage, faster, secure, ideal for advanced uses like payment and ID cards.
Type 5: Moderate to high storage, long range, used for inventory or access control due to extended range.

Choosing between them depends on your specific needs for data storage, security, read speed, and read range.

Type 5 chips work well on small sizes. We are using the small 10mm on the website here and it works well compared to the 15mm ntag chips.
