NFC Reading vs. Code Scanning

Summary

For processing high-value & high-volume assets (50+ items) regularly. NFC tags save time because reading is faster than QR code scanning. While more expensive, costs may be saved in the reading time.

Pros

• Transaction Speed - Tags are read instantly when touched by a dedicated reader, and the device is ready for a new scan right away.
• Costs - Quick scanning and data input saves employee hours and money.
• Line of Sight - Tag does not have to be in the reader's line of sight. Items can be scanned while inside an item casing or packaging.
• Tag Size - NFC tags can be very small and do not need anything printed on them - an advantage for small items.
• Unique - Difficult to duplicate and can be associated with very specific items.
• Durability - Durable and last forever. Difficult to corrupt or destroy.
• Reusable - Can be reused with write capability.
• Reading Range - Reads from 0 to 50mm away, depending on the reader.

Cons

• Price - NFC tags are more expensive than QR Code labels.
• Encode Tags - NFC tags need encoding one at a time using NFC tag writer applications by purchasing special software or outsourcing for mass encoding.
• Reading Range - must be within 50mm to scan, depending on the reader.

Summary

Barcode scanning is ideal for processing a high volume of inventory regularly and when fast, cheap, and convenient labeling is required.

Pros

• Price - QR code labels are substantially cheaper than NFC tags.
• Encoded Labels - QR Codes are easier to produce and print.

Cons

• Write-back - There is no write-back capability.
• Durability - Barcodes are subject to damage.
• Reading Range - Requires visibility to the barcode. When multiple barcodes are present, pinpointing the specific barcode to be read can be difficult.
