I'm in the process of working with a group of merchants who are used to using their shop terminals to run the cc payments and are very adverse to maying any % fee to an on-line transaction fee.
They suggest that we send them half the cc number by email (even breaking it into 4 digit chunks within the email. And then their needing to log onto to the system to recover the 8 other digits and the validation date.
Apart from the hacking possibilities it opens up the the pirate world, is that possible even legal ?
