''so in my case what will happen after i use the whole 1GB of data? it will stop working right and i can throw the sim? ''

Well, you can throw away the SIM or keep on using it. After the 1GB is used up or 30 days are gone you get a message. Then you are on the default rate for data (0.10 CHF for 1 MB), if you still have credit on the SIM. Or you can top up and buy another package. The SIM stops working for data, calls and text when all your credit and allowances on your SIM are gone.

''btw, why passport is needed? what's the reason behind that?''

In many countries SIM cards have to be registered on the name of the owner. That's for security reasons. Unaccounted SIM cards (= anonymous SIMs) are considered as a threat. Switzerland is very strict about this. You will only get a SIM card when you show your passport and give them your name, address etc. at the place of purchase. So you should be careful about giving it to someone else later. If this really improves security, nobody can tell.
