I used a saline glitch trick in the 90s. I cannot remember the exact sequence of events, but one injected saline into the coin or bill receptacle, which made the sensor believe money was being continuously inserted into the machine. This method had the benefit of clearing the machine of change after purchase since it registered the candy bar was bought with a substantial amount of money.
replyClearing the machine of money it already had sounds way more likely to get you into trouble than getting a free coke, I'm not so sure that's a benifit
replyWe just unplugged our vending machine with similar timing.
replyThat is not free, that is stealing. It's like going to a grocery store and calling it a hack that you can walk around the registers and leave without paying.
replyTrue. So sad to think that hackers are exploiting - and yes, there can be no doubt, this is EXPLOITATION - weaknesses in coin-operated services. I weep to think how far has this once-noble vocation has strayed from its roots ...
replyWow. We were like cave men in comparison shaking the machine with 2-3 people to knock a can out of the racking.
replyWe used to get free phone calls in phone booths by sticking an unwound paper clip into the earpiece and touching the other end to the coin box.
replyYou could do the same by wearing wool socks and shuffling around for a minute before touching the coin slot!
