Verifone/Ingenico Data Logger

I need a software that can read and store the data from a POS device (wireless like vx670) tracks 1 and 2 plus PIN. Would be great if it logs date and time as well. ***I DO NOT PAY UPFRONT. *** I will pay you very good once it is done and proved that it works. It will not cost you anything. Even willing to pay more if device is working fine (up to 2000$). I am looking in long term business and i need data loggers like this for other devices as well. Thank you for your responses and looking forward in doing business with you! Cheers
