HI, this is a quick guide of what to do if you find one of these:
1) type the url in your web browser and enjoy the ride.
2) use it as a bookmarker.
3) the akaUNO card is great for filters [no smokers go to number 3].
4) you can take some notes [phone numbers, memory maps, write the lyrics for your next song...]
5) or if you wanna get rid of it, you can either put it in a different place from where you founded it, leave it inside a mailbox [postman/postwoman start in number 1] or throw it in the recycling bin.
only orientative, do what suits you best,
