I found this rather interesting paragraph:

"DATA COLLECTION & MANAGEMENT
SynerTAGs collect useful data when scanned by your customer's smart phone which is then converted to a PDF statistics page."

With so many concerns these days about consumer privacy, etc., I would definitely want to know what's being collected and how it is used.

And as to Michael's question about whether or not it is actually being verified, there isn't any way short of previewing the decode and making sure it is going where it is supposed to, and how a user is to verify this is beyond me since it would be very difficult for them to know what the decode should be.

The thing to keep in mind about barcodes regardless of symbology is they all boil down to machine-readable text. They were created pretty much as a more accurate alternative to OCR.
