Folks, I see many US business still asking for credit card details over fax. Basically they want me to write my credit card number, address, expiration date, security code, etc and fax it over. How secure is this practice? Do they realize what they ask is the same as asking someone to hand over their ATM card and PIN code? I mean serious their staff could take my card details and go shopping online for stuff like domain names, software, ebooks, etc which don't need physical deliveries. Plus when we enter credit card details online does the merchant see everything? Is it the same as giving the details via fax?
