The POS (Point Of Sale) Data Logger is similar to a portable magnetic stripe reader in that it logs data and can be used for memory back-up in case of power failure. This device quickly connects in-line on the POS terminal. Iam sure you have seen these POS terminals in just about EVERY store & some terminals have a computer-like keyboard with a built-in credit card reader, others have a separate credit card reader and some even have a credit card reader with a PIN pad where you enter your PIN # if you are using a debit card. Iam looking for a person who can convert a keylogger to Point of sale data logger which can capture the card details when a card is swiped while at the same time retain the pin number when it is entered. I have tried purchasing these data loggers but they only work with a normal keyboard and do not capture the card information when a card is swipped on a point of sale terminal. Bid only if you are sure you can do this job and can finish the job ASAP.
