As a solution, there could be better looking cash registering machine with fresher looks and an easier to use software in which you can register objects faster and easier. As a result, this can lead to people paying for their products so much faster that the time spent in the line to pay will be dramatically shorter.
As a solution, there could be a platform in which is a full marketplace but instead of buying the product completely, you rent it for a certain amount of time and you pay the one who gives you the object to keep it and use it well. If it breaks, you pay a fee so the buyer won't mishandle it.
As of now, I don't see any existing solutions. So the best thing to do is to make this process on a mobile application in which you scan in a QR code your check with your phone and it also becomes your personal bank account. It would be a pretty nice idea for people who want to check their money in a quick and easy way. I will check the legal issues that might happen later on, so I want to make sure that the process is supported by the government.
The people who need this are students who want to feel more confident and prepared for the exam, family members who can't help their children because they are too busy and tutors who want to do this as a side-hustle.
As far as I know there are no existing solutions at the moment for this need so I think this will be an excellent solution for everyone to use since this will be the first app for reserving parking spots. Once they use the app, they could go to the store in an quicker way than ever before.
And also, by making a free problem solver (the solution), homework answers will be readily available for people for free. There will be more features in upcoming updates, some with a premium subscription according to the number of people using it (remember that the homework solver will always be for free).
