You should consider replacing all card readers with PCI compliant EMV PIN Pads.  Contact Execu/Tech for more information.

Shift4 Card Readers (Non-EMV)

• This information does not apply to EMV PIN Pads. See Shift4 EMV.

• For non-P2PE devices, any USB card reader that works in Keyboard Emulation Mode will work. 

• ​Swipe data must be sent WITHOUT a Carriage Return between tracks.

•  If your card reader is inserting a carriage return between tracks, the swiped data will look like this:

 %B5432000000003332^MC/FAKE NAME^1812999999?
;5432000000003332=1812999999?

​

 If the card swipe data looks like this ▲, then it might not work.

• If your card reader does not insert a carriage return between tracks, the swiped data will look like this:
  

This is the correct format. This is what the swiped data should look like to be compatible with our Shift4 i4Go V2 interface.
