Yesterday, an important question appeared at almost the same time on Tweakers.net and Security.nl. It is about 2D barcodes on some packages delivered by PostNL. Some of these – I call them Data Matrix, as that is what they are – seem to include the e-mail address of the recipient.
The posts caused some uproar, and in order for myself to understand what is going on and what questions should be asked to PostNL, I wrote this blog post.
In any case: always remove parcel labels before disposing of the parcels, then destroy the labels. This has always been good privacy practice and will stay that way forever.
Regrettably, Tweakers.net blocks both the Wayback Machine and Archive Today, which makes their information ephemeral. Therefore I archived some of the Tweakers.net information in the gist [Wayback/Archive] “E-mailadres van ontvanger kan in PostNL barcode staan” archived from https://gathering.tweakers.net/forum/list_messages/2327530/0 · GitHub
