Since he has found the "ticket" and it has the website from the DB printed on it, I assume he was riding on a train or some sort of transport provided by the DB.

Since this "ticket" has specifically the site for paying penalty for a non-valid ticket, I assume, this is what he was given by the ticket inspector.

If the OP still wants to pay, the DB has specific information for this:

"IFS/Service Center FN, 76518 Baden-Baden
Commerzbank Baden-Baden
BLZ 662 400 02
Konto-Nr. 115 507 600

Für Bezahlungen aus dem Ausland:

S.W.I.F.T.-BIC-Code: COBA DE FF
IBAN: DE02 6624 0002 0115 5076 00"

The last two lines include the codes you will need to pay from outside Germany. They also ask you include the "ticket" number.

If you have something like this (http://www.willizblog.de/blogpicts/f...cherhebung.jpg) the "ticket" number is at the top and has the label: "FN-NR.:"

They also say you have only 14 days to pay before more penalties are added, but since you do not live in Europe, perhaps they will forget that.

Good luck.
