When to Use Aztec Code vs QR Code

• Use Aztec Code for: transportation tickets, boarding passes, small labels, space-constrained printing
• Use QR Code for: marketing materials, URLs, general-purpose scanning, consumer applications
• Aztec Code advantage: more compact for small data, no quiet zone required, omnidirectional reading
• QR Code advantage: more widely supported by consumer apps, better for large data

Use the Aztec Code Generator at TechConverter.me to create transportation-grade barcodes for ticketing systems, event management, and any application requiring compact, reliable 2D barcodes.

Input data (airline boarding pass):
  M1SMITH/JOHN         EABC123 JFKLHR BA 0112 123Y001A0001 100

Aztec Code settings:
  Error correction: 23% (standard for transportation)
  Size: auto (calculated from data length)
  Output: PNG, 300x300 pixels

Result: Compact 2D barcode containing all passenger
        and flight information, scannable from phone screen
        or printed ticket.

For small amounts of data, Aztec Code is more compact:

Data: "TICKET-12345"

QR Code:
  Minimum size: 21x21 modules
  Requires: 4-module quiet zone on all sides
  Total with quiet zone: 29x29 modules

Aztec Code:
  Minimum size: 15x15 modules
  Quiet zone: Not required
  Total: 15x15 modules

Aztec Code is ~27% smaller for this data.
This matters when printing on small ticket stubs.

Error correction options:
  5%  — minimum, maximum data capacity
  23% — standard for transportation tickets
  36% — good for printed documents that may get damaged
  50% — high tolerance for damage/obscuring
  95% — maximum error correction, minimum data capacity

For digital display (phone screen): 5-23%
For printed tickets: 23-36%
For outdoor/harsh environments: 50%+
