Is scanning an ID barcode enough to verify someone?
Scanning the barcode on a driver's license reads the data encoded on that card. It does not show that the card is genuine, unaltered, or that the person holding it is the person it describes. Pairing a document check with a live face comparison adds a test of whether the person present appears to match the ID photo. Neither method guarantees identity, safety, or the absence of fraud.
What a barcode scan actually does
Most North American licenses carry a PDF417 barcode holding the same name, date of birth, and address printed on the front. A scanner decodes those fields. Counterfeit cards routinely carry valid-looking barcodes, because the encoding format is public. If a fake card is printed with a consistent barcode, the scan agrees with the fake.
A barcode scan is useful for speeding up data entry and catching crude mismatches between the front and back of a card. It is not, on its own, identity verification.
Side by side
| Question | Barcode alone | ID plus live face |
|---|---|---|
| Reads name and date of birth | Yes | Yes |
| Checks the document for signs of tampering | No | Depends on the provider's document checks |
| Tests that the holder resembles the ID photo | No | Yes, with error rates |
| Tests that a live person is present, not a photo | No | Attempts to, with limits |
| Proves honesty, ownership, or safety | No | No |
Limits of ID plus live face
- Face comparison produces false matches and false non-matches.
- Liveness detection reduces, but does not eliminate, spoofing with masks, screens, or deepfakes.
- A genuine ID used by its genuine owner tells you nothing about that person's intentions.
- Supported document types and countries vary by provider.
Limits to keep in mind
- No identity method is fraud-proof. Treat any result as one input to your decision.
- Truvee does not claim to detect every forged document or spoof attempt.
