ID works in-person but fails online age verification - Why?
Yeah online verification services parse the full PDF417 string and cross-check it against AAMVA compliance rules, plus they hit databases. In-person scanners usually just check if the barcode is alive and pass a basic checksum validation. Your Ohio might scan fine at a register but the data parsing throws a red flag the moment a real verification service reads every field. Not much you can do about that route honestly.
I've run into this same wall with online verification. It's a completely different beast—in-person just checks the basic stuff, but online services run the barcode data against actual databases and algorithms. If any field doesn't match their expectations, it throws a red flag, plain and simple. My guess is they're also checking for AAMVA compliance in the PDF417 string format, so even a tiny discrepancy causes a data parsing error. At this point, if a site requires that, I move on—not worth the headache. You're not alone.
Yeah, that’s pretty common. In-person scans just check the barcode holds up–maybe basic checksum validation–but online verification digs way deeper. They’r probably checking the PDF417 string format and running it through something like the Intellicheck database, which spots mismatches real quick. If the barcode is dead or doesn't line up with AAMVA compliance specs, it throws a red flag automatically. I'd stop trying with those sites; it's not built for that.
