Identification Methods
Magnetic Swipe
A Hash is created from the already present magnetization pattern on the the stripe. Works with most standard magnetic cards without effecting there normal use. Does not work with 100% of the tested local transit tickets (MTA and BART). However, it is not advised to use Cards which could be harmful to you if the information on the stripes gets in wrong hands (like Government issued IDs or Credit cards). We can not exclude the possibility that Hackers could excess the System storing the Data.[1]
