There are quarrelsome situations where most often mobile shop owners have conflict with customers for writing confusing numbers in notebook for mobile recharge.It happens quite often & everywhere-in small cities, metros & even villages.
I have proposal for development of low cost digital hardware device with keyboard to enter data & numbers entered should be seen on Display, connect the device with PC to log data. From where to outsource body parts, display types & cost, connectivity protocol cost issues, keys & other important factors controlling cost of device.
Let us form a team. We need to have technically strong team.We do require micro controller & interfacing hardware. Which micro controller best suits the requirement…? As it is very simple application, easy to use cheap controller can be of use. We need to check if we need OPC application to read data entered.(I am not sure about OPC)…what is the minimum requirements of keys & display…? What about cost factor of body parts?What are cost & pricing parameters of communication protocols…? Should we use wireless data transfer protocols ? Let us work systematically…make table & chart for studying all relative data about parameters like keys cost, display cost, available body parts cost, various controller cost, OPC cost & finally cost of communication protocols.
If we keep in mind concept of manufacturing minimum quantities(as is vital for any sector), cost effective production strategies are very important here. But initially we can not take risk of producing in bulk.
Friends there are thousands & probably lacks of mobile recharge shops across country.This idea is really excellent & can opens doors of your learning journey to be very successful entrepreneur ! Work on it…mail me details…
Any inputs are appreciated.
