A Hash is created from the already present magnetization pattern on the the stripe. | * TL;DR you need a card with a black magnetic stripe on the back, such as a credit card, phone card, gift card, or anything that can be read by our reader. Unfortunately BART cards do not work. | ||
* The card you want to use must be registered into the system so that it will allow you to open the doors. | |||
* The card DOES NOT need to have your name on it or be "valid" in any way, it just needs to have something recorded on its magnetic 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.<ref>As a matter of fact we can guarantee that. </ref> | Works with most standard magnetic cards without effecting there normal use.

==== BART cards are so easy to get, why can't we use them? ==== | |||
* BART cards are not encoded using the bit-pattern standard that our magnetic stripe reader recognizes, and so it can't read them at all. Our reader double-checks every stripe it reads and only reports a reading if it is sure it read the card correctly. | |||
* In future, we could replace the card reader with a read-head attached to the microphone jack of the computer, and use a fancy program to read and recognize ANY card people choose to use. Search github for "magnetic stripe" | |||
