The Purpose of Change Machines
"I think you're talking about two types of machines, at least in the United States. The term change  machine usually refers to a machine that accepts large denominations of currency and returns an equal amount of currency in smaller bills or coins. Typically these machines are used to provide coins in exchange for paper currency, in which case they are also often known as bill changers. Exactly what bills or coins these machines return depends on the machine. Read the instructions on the machine to get the details (they're usually right on the machine). For example my apartment building has a machine that converts small bills like ones and fives to quarters, since the laundry machines only took quarters. The other type of machine are coin-cashing machines, like the Coinstar machines you might see at a grocery store. Many banks used to have these machines as well although in my area they're few and far between now. These machines perform the opposite function of the traditional change machine and convert smaller denominations (mostly coins) into bill form. For example if you dump all your accumulated pennies into the machine, it will probably give you bills and larger coins like quarters, dimes, nickels in exchange, after subtracting a small fee. I've heard that now, some of these machines may give you a gift card of some kind instead of bills, although they'll still subtract a fee from your original amount, usually. Once again just read the instructions and they should tell you. When my bank had one of these machines, they didn't charge a fee as long as you were a customer at the bank. I'm sure that varies from place to place and bank to bank though. Wikipedia's article has this to say (see the article for references): In some sections of the U.S., regional banks have begun offering free coin-counting services in the amount of a gift card. Refunds are often given in cash rather than in the form of a gift card. In some cases, it is not even necessary for the customer to have an account at the bank; the free service is offered as a way to attract new business from individuals who are not current account holders. TD Bank's ""Penny Arcade"" coin counters were free and available to both customers and non-customers in many branches, but as of November 2010, the bank charges a 6% fee for non-customers to use the machine."
In the Rocky Mounttain, for security purpose, it is important to check all the baggage. It is also important to find the best escape routes in case of any emergency, look for the two nearest emergency exits. Static Balancing of aircraft is also very much important as having extra baggage and extra weight can able to create many problems for the aircraft. It sometime also happens that while carrying extra luggage can lead to have some unconditional accidents while landing or take off of the aircraft. For doing the deice form the surface of the aircraft a machine is used for spraying the chemical and  the machine works very fine to remove the ice from the surface of the aircraft.

The banks change software with physical access to the ATM, the type of access the public doesn't have without breaking into it and setting off an alarm.  And you linked a 4 year old article.  You think all ATM machines are still that vulnerable to physical attack?    I don't know where you live, but ATM machines here are very new.  And even if they run Windows XP, so what. **John Vincent Atanasoff**  John Vincent Atanasoff (October 4, 1903 – June 15, 1995) was an American physicist and inventor, best known for being credited with inventing the first electronic digital computer.  Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer. His special-purpose machine has come to be called the Atanasoff–Berry Computer.  ***  **Touchscreen: History**  E.A. Johnson of the Royal Radar Establishment, Malvern described his work on capacitive touchscreens in a short article published in 1965 and then more fully—with photographs and diagrams—in an article published in 1967. The application of touch technology for air traffic control was described in an article published in 1968. Frank Beck and Bent Stumpe, engineers from CERN, developed a transparent touchscreen in the early 1970s, based on Stumpe's work at a television factory in the early 1960s. Then manufactured by CERN, it was put to use in 1973. A resistive touchscreen was developed by American inventor George Samuel Hurst, who received US patent #3,911,215 on October 7, 1975.  ***  ^[ [^PM](https://www.reddit.com/message/compose?to=kittens_from_space) ^| [^Exclude ^me](https://reddit.com/message/compose?to=WikiTextBot&amp;message=Excludeme&amp;subject=Excludeme) ^| [^Exclude ^from ^subreddit](https://np.reddit.com/r/economy/about/banned) ^| [^FAQ ^/ ^Information](https://np.reddit.com/r/WikiTextBot/wiki/index)   ^] ^Downvote ^to ^remove ^| ^v0.21 Do you also want to start charging companies and people for using computers? Excel?  What about any machines? Surely trains took jobs away as they can carry a ton of cargo.  Point is, taxing automation sounds nice, but it's ridiculous. We've been automating things for a long long long time. The type of automation is just changing. The car created tons of jobs.  We have already seen one robot replace hundreds of people in factories.   Automation with robots and AI will not create more jobs than it displaces.  What need is a human when you have a robot doing the work? You seem to be confusing the anti technology people of the olden day with the vastly more intelligent and technologically minded people of today.  You are mischaracterize the student loan debt issues.  A baby boomer leaving doesn't mean they're replacing them. Do more with less is a corporate motto.   Btw if you think serving of these robots will make a ton of jobs you don't know how the servicing industry works. It won't.  You're also ignorant about healthcare costs. Market forces can't fix this nor will they.  If I held a gun to your head and told you to pay x you will. That's basically the same as you have cancer now here's your bill.  For a millionaire you're not so great at reality. I'd argue that society would likely moved to 100% online delivered to your doorstep before this actually happened, thus removing the need for physical locations, but as someone who actually works at Amazon, yes 100% automation is their long term goal. There are a number of factors here. 1) It's important that there is human oversight on the system. At one level someone needs to be monitoring the computers that manage the trading to be sure they are functioning. At another level someone needs to be making judgement calls on important but rare events: when you you suspend trading in a stock? When do you close the stock exchange entirely? It is alleged that unsupervised computer trades were at least partly responsible for the May 2010 selloff. Even if that's unproven, would you really want those unsupervised computers trading with each other for a couple of days? Or even for a couple of hours? 2) Providing 24/7 trading would increase the cost of running a stock exchange, but with only a tiny improvement in liquidity. 3) If the stock exchange ran 24/7 then traders would have to run 24/7. That would add hugely to the cost of trading. 4) The people who would really suffer would be day traders - because there would no longer be such a thing as a day trader. If you were a sole trader then you would need to monitor your investments 24/7, or risk waking up in the morning to find one of your stocks had plummeted overnight. Traveller's cheques. That's exactly what they were intended for. Their usage has dropped a lot since everyone can use ATMs in foreign countries, but they still exist.
