It takes several swipes before the credit card reader reads the card properly

Cause: The Card Reader's transmit speed is too fast. If you are using a USB Adaptor (Non-ID Innovations) this is a common problem because USB Adaptors are not prepared to handle the data as fast as the Card Reader can transmit.

Solution: Slow down the transmit speed on the reader. Use Windows notepad to repeatedly swipe credit cards to verify that the data is received the same, each time the card is read.

Steps: With your keyboard connected to the card reader and using Windows notepad or some other program you can type in follow these steps:

<Left Ctrl> <CapsLock> <Right Shift> <Backspace> This will display the prompt "Press F1-F10 for options"
Now press the F1 key and hit the down arrow until you see "Transmit Speed 0 = Fastest:".
Press the right arrow to slow down the transmit speed on the reader, try 6 first.
Now press and hold down the following keys: <Left Ctrl> <Escape> and release both keys. This will display the message "Setup Complete Changes saved".
Test your card output in Windows notepad, if this did not fix the issue then repeat Steps 1 through 4 but increase the transmit speed value each time you have to repeat.
