The pay phones in which we have to drop the coin in and then we are able to make calls. These are often evident at railway stations and other places. Does anyone have any idea as to how they work?
banerjeerupak said:i do understand that they are just vending machines. Could you tell me the mechanism which is used to recognise a particular type of coin in these sort of machines. Wikipedia does not have this info. I have also tried googling it.
berkeman said:Go back to google, and google coin mechanism. You will get lots of helpful hits.
I do want to warn you, though, that if you are looking for ways to spoof coin-operated vending machines, you will get no further help here on the PF.
banerjeerupak said:I'm not trying to spoof anything. I was planning to use the same mechanism to operate a automated entry to parking lots for my minor project. I have been googling the stuff. The hits are not of much use, the mechanism is never explained enough to understand its working. Mostly it is vendors selling the stuff. Which is of no use to me.
The purpose of "Payphone Mechanics: An Investigation" is to examine the inner workings of payphones and understand how they operate. It aims to uncover the technology and mechanics behind these devices that are often taken for granted in our daily lives.
The investigation utilized a combination of field observations, interviews with payphone technicians, and analysis of technical manuals and schematics. Additionally, experiments were conducted on individual payphone components to better understand their functions and how they contribute to the overall functioning of the payphone.
The investigation revealed that payphones are complex devices that rely on a combination of mechanical, electrical, and communication systems. The most crucial components of a payphone include the coin mechanism, handset, keypad, and circuitry. The investigation also uncovered the various security measures and maintenance processes involved in operating a payphone.
While payphones may seem like outdated technology, they still play a significant role in providing communication access to certain communities. Understanding their mechanics can help improve their functionality and reliability, as well as inform future advancements in communication technology.
Some potential future research directions related to payphone mechanics include exploring the impact of digital and wireless technology on payphone operation, investigating the use of payphones in emergency situations, and examining the global use and accessibility of payphones in developing countries.
