Code 400C

Isabella Gumm Updated by Isabella Gumm

Code 400C means No Identity + Card reader not found: The store is having trouble verifying its serial number or KID while also having trouble connecting to the card reader.

For the identity issue:

Please contact Byte Technology's client success team at with a phone number and a time to call you.

For Card reader not found:

  1. Power Cycle (unplug all power cords from the surge protector for about 20 seconds before plugging them back in)
  2. Check the lights on the credit card reader

If the problem continues, please contact support@bytetechnology, and share with us what steps you have taken and your findings.
