There seems to be some confusion (particularly on the part of the original poster) regarding this post:
Scanning the codes on each ticket shows the purchase dates and times:
- BDK-CBG: Purchased on 22 Jan 2025 at 06:12
- FPK-BDK: Purchased on 22 Jan 2025 at 08:11
This seems to indicate the FPK-BDK was purchased after the penalty fare notice was issued.
The above information can be obtained by scanning the barcode with software that is freely available (
https://eta.st/tickets/ ).
The barcode has since been redacted, due to privacy concerns by the original poster, however the information stated in the post quoted above was
not a breach of privacy, as the information was available without access to any industry systems.
For the avoidance of doubt, the barcodes on train tickets are
not QR codes and cannot be read by a QR-only barcode scanner, or even an Aztec scanner that does not have the relevant decryption keys.
These barcodes are Aztec codes, and can only be read by software that can read codes of that type.
Additional information, such as scan history, can be read
only by people who have access to the database that stores that particular data, and this should not be published on the forum (at least not without the consent of the ticket holder), but that has
not happened here.
A bit more information regarding key differences between Aztec and QR barcodes can be found below:
Aztec barcode vs QR code differ in appearance, features, and functions. This article makes a head to head comparison of the two barcodes.

Aztec barcode vs QR code? At a glance, they look almost identical: square, pixelated, black, and white. But their differences can be narrowed down by zooming into their features and functions.
...because of the strategic placement of the finder pattern at the center, an
Aztec barcode is way easier to read than a QR code.
