  • 30 characters in the bar code (www.nationalband.com/laser.htm).
  • The smallest codes cannot be read using a smart phone because the bar code is too dense.

Less Dense Barcodes

  • 6 characters in the bar code (AB1234).
  • All the codes can be read using a smart phone because the code is not that dense.

Need to have editable info on your barcoded tag?

Many people need to keep a single barcode on a particular tag and application, but need the ability to edit the information returned when the barcode is scanned. If that’s you, here’s a solution using webpages!

  1. Setup a website on your domain (ie: www.nationalband.com)
  2. Create pages for each tag you want barcoded (ie: Tag 1 Barcode = www.nationalband.com/tag-1)
  3. Add your data/info to the webpage (ie: “Specs for Machine A: xxxx” on www.nationalband.com/tag-1)
  4. Edit your info as needed, but always use the same webpage for that particular machine and tag
  5. Repeat for each additional tag/machine (ie: Tag 2 Barcode = www.nationalband.com/tag-2 = “Specs for Machine B: xxxx”)
