@stitchnkitty - Ceon Manual Card never was intended, is not, and is most unlikely ever to be PCI compliant. I refer you to Conor's original comments in his manual for the plugin...

Please note: We take no responsibility for the usage of this software, nor its compliance with any terms and conditions the store merchant may have signed up to, it is up to the store to make sure it is compliant with all relevant security protocols and laws, e.g. to be PCI compliant etc.
FYI, we have been advised by several of our UK clients that as a condition of being granted a Merchant Account, their banks are now demanding that card details are ENTERED on the payment gateway server, and should that become universal (as it no doubt will in time) then that will consign not only the Ceon Manual Card, but also his commercial offering of Ceon Sagepay Direct to history.
