I am talking about some old guy trying to sell his products...
If that old guy cannot do this simple line of code and download a proper wallet, he should not be selling his products.
There you go:
<a href="bitcoin:33jr6swgJxHwyFTgXKcv7kbKSy4du8Yt8r?amount=1">Pay here</a>
It is much harder than this line to accept paypal or accept visa in your website. Bitcoin is easier than those methods online. Easier and cheaper.
Example 1: he places an ad in the newspaper : I made a digital book send xyz BTC to address ABC ,once payment is sent you can download the book ...without the need for him to install complex software or to use third party ...
If he uses any decent wallet, the wallet will pop up in his mobile when he receives funds. No need for complex software.
Also Timmy is in the USA and Granny in Germany ...Timmy has to wake up Granny in the middle of the night to send her BTC for a jar of Cherry Jam like you want to...
Nah, I think you just don't understand how bitcoin work. Granny can give the address to Timmy before she sleeps.
If Granny were using a bank account, she would need to give her account information before going to be also, otherwise she would have to woke up in the middle of the night. lol
