we need you to make verifone eftpos programmed especially chip because when we copy chip from card including input pin doesn't work in atm because there is algorithm program in chip that code keep changing and generate new code but somehow for a code programmer be able to come up with new method for that code .
I try to explain it again.
Before we only need copy of magnetic stripe and pin for card to work
Then since then chip been implemented if we copy information from chip it does not work because of generated code keep changing every time user use card
Each time get change for example if user use card
Chip has info track 1,2or 3
Then it generate code from terminal for example 555
And pin of the card has not change is still the same for example 1234
Next time if the user want to use the card and info still the same has not change pin the same and card info the same , but the only thing has change its chip on card generated new code so old code it won’t be used any longer for example 555 become a new code .
I hope you get what meant and if you Google it you may understand it better.
as i mention before we have sdk but its large to upload it through email.
however its not issue with i just want to know you be able to write programmed can fix all this .
and if you can let us know how much this project will cost and time frame .
So again i can give more example to understand what i mean :
we need to programmer eftpos offline or online iot doesn't matter :
When user use card in machine it options appear for example :
Select option card ( saving , credit, check)
User put pin number ****
Software we had been implemented in device machine recording the every data
Later on we copy data on other cards and let user use it atm for withdrawal since cards has chips
It doesn't work even if user has whole copy magnetic strip pin etc .
Because chip code been generated to new code and old code wont work , but there is method can be programmed .
I can send you full sdk and if you like, and if you machine for testing i can arrange that too
I only send you some files been programmed but i can explain full details if you still don't understand
If you accept project we can give you good offer

[login to view URL] is that you? :) Anyways, i can def assist. Let me know the details. As i have worked in this field for a while in terms of such POS such as in Ingenico SDKs. Thanks
Hello there! All you need here is clear AI algorithm that my team will provide This is not one-person project I would be happy to review full sdk Thanks Andrew
