How much data can an NFC store compared to QR codes or Barcodes?

NFC tags are best for small, dynamic storage with easy read/write capabilities. Whereas, QR codes offer moderate storage capacity, making them suitable for a wide range of applications, especially where quick scanning is needed. Finally, Barcodes vary widely in capacity, 1D barcodes are limited, while 2D barcodes can store more data but are less common in everyday consumer applications.

The storage capacity of an NFC tag typically ranges from 48 bytes to 1 megabyte. Common NFC Tags like the NTAG213 have around 14 bytes of usable memory, while more advanced tags like the NTAG216 can store up to 888 bytes. These tags would be ideal for storing small amounts of data such as URLs, contact information or small text messages.

QR Codes have a larger storage capacity, typically ranging from 3KB of data. This translates to approximately 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. QR codes are commonly used for URLs and contact information and other data that can be scanned quickly by smartphones.

Regarding Barcodes, 1D barcodes have a limited capacity and can only really store between 20-80 characters, these are typically used for product identification, such as UPC codes on retail items. 2D barcodes (like Data Matrix and PDF417) have a much higher level of storage capacity, with a limit of around 3,116 numeric characters, 2,335 alphanumeric characters or 1,556 bytes of binary data. Use cases for 2D barcodes range from being used in logistics, inventory management and other applications requiring more data storage.
