Clue 1
You've probably already noticed that the URL as written doesn't seem to work... So it must relate to something else.
Clue 2
The word "pmats", since it doesn't work, is probably pointing you in the right direction.
Solution
The word in the URL is the word "Stamp" written backwards. So you should look to your stamp for help completing the proper URL.
Clue 3
It's all right there, but unfortunately it isn't very "straightforward."
Clue 4
In fact, some would say this puzzle is downright backwards.

Clue 1
Have you already discovered what other element on the card is pointing to the stamp? If not, you should work on the rest of the card and come back to this later.
Clue 2
Not only is the word "pmats" in the URL pointing here, but it's giving you a clue that'll help you decode it.
Solution
The two items needed to solve this puzzle are knowing that it's hexadecimal (based on the shape in the background and confirmed by the format it's written in) and knowing that it's all backwards.
Clue 3
A second clue can be found in the background behind the numbers... That shape will point you to a certain "code" of sorts...
Clue 4
Hexagon... What well known numerical system also starts with "hex"?
Clue 5
It's hexadecimal alright, but the way it's written it doesn't make sense. Don't forget about the URL. It didn't just say "stamp," did it?
