At the recent Paypal X Innovate 2010 Developers Conference, held in San Diego, CA in late October, Paypal Labs showed off their proof-of-concept change-free gumball machine.

A clever combination of PayPal, QR codes (a type of barcode that can be scanned on a smartphone and can contain various kinds of information, including web links), smartphones and Twitter, the gumball machine instantly debited a PayPal account and dispensed a gumball to anyone with the capability to read QR codes on their mobile phone.

... and when you chargeback you are chased by men in a black van who forcefully remove the gum from your mouth.

LOL
No!
We're talking about PayPal.
They're "attached" to your bank account (aka a co-owner of your bank account)... which means, they'll simply take the $0.25 out of your bank account -- even if it causes Your SAVINGS account to be overdrawn, and results in $75 in fees from your bank...
Don't worry.  PayPal will get their $0.25 every time.
They're evil bastards.
Which is one of the reasons I support Bitcoin so much, and created http://bitcoinme.com
.. because of how evil PayPal is.

No.  After you've spent $8000 on your PayPal account, PayPal REQUIRES You to "attach" your PayPal account to a bank account (not just a credit card).  This way they can withdrawal from that Account any time they want - even if they overdraw your bank account.   PayPal doesn't care.
