Why would running a credit card require wired internet?
Nowadays we have WPA2 and HTTPS is more common. But I still prefer an ethernet cable.
SSL has been used for online card transactions for longer than Windows 95 has been out, it was basically invented for that purpose.
Was there really a time when WiFi was in common use and people carried out financial transactions over HTTP?
HTTP over wired is not secure, either.
Amazon launched in 1995, and SSL only launched the same year, so they might have taken plaintext credit card info for a short while.
That's a technicality, though.
HTTP over wired is not secure but it requires physical presence rather than proximity to sniff. It's kinda like security by obscurity.
Perhaps credit card point-of-sale devices don't have WiFi?
Saying that CC terminals require Wifi because not all of them support Wifi is like saying that Laptops require wifi because not all of them have built-in Wifi.
> "...or running credit cards, still often require wired..."
A statement of exclusivity if one overlooks the weaselly use of the word "often".
> Why would running a credit card require wired internet?
A question of such exclusivity.
> Perhaps credit card point-of-sale devices don't have WiFi?
A defense of exclusive statement, evidence provided: no POS has wifi.
> Square operates entirely over WiFi...
A rebuttal to evidence.
> ...but that doesn't mean most devices do.
An attempt to ignore the original and subsequent defense of statement of exclusivity.
I have no wired connection whatever. My phone is 4G and I connect to it over wifi.
I regularly watch streamed HD video Broadcasts at about 3-5gbps constant, it maxes out at about 11Gbps.
I would be most annoyed to find myself in a hotel where my laptop was being prevented from connecting with my phone.
