1. I don't have any pressing need to buy a product at such a low price point, and don't see any need to do this in the future.
2. My credit card works wonderfully, and if a retailer pisses me off, I'll phone them and it'll be reversed no questions asked.
3. Again, I (and most other consumers) already have a solution to buying something online that is almost perfect from my perspective. I have three of them in my wallet sitting with me at this very moment (actually, my wallet is a bit of a problem you could look into, especially in the summer).
I don't need paypal. I don't need pretend currency. I don't trust you to get anywhere near my actual bank account. I have several security options with my credit cards that I'm comfortable with.
I personally don't really care that it costs you x amount to take my credit card as a retailer. I've already factored in all your business costs into my evaluation of the price of your product. I also don't care that your employee demanded a raise last week, you need to buy a new computer or that rent is going up. These are your problems.
Again, do you understand that as a consumer, I view my credit cards as almost the ideal product to conduct business on the internet? You're trying to fix a problem that I just don't have by providing me with a solution that I just don't need.
2. 100 keypresses per transaction[1] != 'ideal solution'
There's plenty of room for disruption in this market still. No-one's asking you to become one of those disruptors and we won't be taking away your credit card. You can keep it. Just like all those people who prefer cash to credit cards can keep their cash.
[1] Card number, SSN, expiration date, address, address line 2, City, County, Postcode. Maybe emailaddress, telephone number. Roughly 100 key presses to enter that lot
Now you know what we're all talking about and can start giving a flying fuck!
