Flytoget fra Oslo S til flyplassen ga meg en billett med -magnetstripe. Påtrykket finner jeg følgende informasjon:</p> - -<pre> -Flytoget Airport Express Train - -Fra - Til : Oslo Sentralstasjon -Kategori : Voksen -Pris : Nok 170,00 -Herav mva. 8,00% : NOK 12,59 -Betaling : Kontant -Til - Fra : Oslo Lufthavn -Utstedt: : 08.05.10 -Gyldig Fra-Til : 08.05.10-07.11.10 -Billetttype : Enkeltbillett - -102-1015-100508-48382-01-08 -</pre> - -<p>På selve magnetstripen er innholdet -<tt>;E?+900120011=23250996541068112619257138248441708433322932704083389389062603279671261502492655?</tt>. -Aner ikke hva innholdet representerer, og det er lite overlapp mellom -det jeg ser trykket på billetten og det jeg ser av tegn i -magnetstripen. Håper det betyr at de bruker kryptografiske metoder -for å gjøre det vanskelig å forfalske billetter.</p> - -<p>Den andre billetten er fra Hurtigruten, der jeg mistenker at -strekkoden på fronten er mer brukt enn magnetstripen (det var i hvert -fall den biten vi stakk inn i dørlåsen).</p> - -<p>Påtrykket forsiden er følgende:</p> - -<pre> -Romnummer 727 -Hurtigruten -Midnatsol -Reinholdtsen -Petter -Bookingno: SAX69 0742193 -Harstad-Bergen -Dep: 09.05.2010 Arr: 12.05.2010 -Lugar fra Risøyhamn -Kost: FRO=4 -</pre> - -<p>På selve magnetstripen er innholdet -<tt>;1316010007421930=00000000000000000000?+E?</tt>. Heller ikke her -ser jeg mye korrespondanse mellom påtrykk og magnetstripe.</p> - - -
