Credit Card reader delete leading characters?

[jkrizan]

Hello,

We are using a Magtek credit card reader as input to the credit card field on WooCommerce POS.  However, when we swipe the card two leading characters like B% are displayed.  Where is the modification made to truncate those uneeded marks for processing?

Thanks,

Hello @jkrizan

You may need to contact Magtek, the manufacturer of the device for information on how to solve your issue.

By default, sentinels are enabled and transmitted. To modify the default settings of a USB Magtek reader on a Windows machine, for example, see below.

First you would need to download and install the demo application from:
http://www.magtek.com/support/software/demo_programs/usb_swipe_insert.asp

Once installed run the application and attach the MSR device. Once the device is detected follow the directions below.

To disable sentinels:

1. In the orange highlighted area check “Auto Add Length” and then in the line below enter: 01 14 03 and select “Send Msg”.

To enable sentinels:

1. In the orange highlighted area check “Auto Add Length” and then in the line below enter: 01 14 63 and select “Send Msg”.

You will then get a response from the device informing you that the command was successful.

After the command has been sent you will need to power cycle the device.
