There are several reasons why SWM tags are far superior than barcodes:
- Barcodes are difficult to scan due to the curvature of a bottle
- Barcodes carry only a limited amount of information and may not properly identify an individual bottle
- Many wine producers recycle barcodes and therefore you aren’t guaranteed that the barcode actually maps to your bottle
- Barcodes don’t contain any error correction making them more difficult to read successfully unlike a SWM Tag that has error correction built in
- Barcodes must be read by a scanner unlike a SWM tag that can be simply be tapped
