Various types of digital cash, electronic money, or crypto-currency can be used, such as Bitcoins provided by the Bitcoin P2P Currency System.
Amazon prepares for Bitcoin?
Amazon was awarded a patent which explicitly mentions crypto-currencies -- and specifically Bitcoin -- as a potential payment method.
Bitcoin integration with PayPal
I said a long time ago that Bitcoin integration with PayPal is possible.
John Donahoe, CEO of ecommerce giant eBay, said he is actively considering an integration of popular digital currency bitcoin with the company's payment processing service PayPal.
This guide contains basic information for cardholders about security of credit card payments. It starts with false statement though: "you have no viable alternatives when buying something online". This is wrong because today major online retailers, in addition to credit cards, accept alternative methods of Internet payments. PayPal and Amazon Payments, which were originally based exclusively on credit cards, nowadays allow payments directly from bank accounts, with the same convenience of instant transactions as credit and debit cards. In fact, they prefer payments via bank accounts which save them a lot of money on interchange fees.
It was unexpected to see the Target's REDcard in the list of emerging technologies, just next to the systems such as Bitcoin. What is so alternative in decoupoed debit card, and why other similar decoupled debit cards are not listed, for example, Nordstrom Debit? It looks like this ad belongs to Target reputation rehabilitation PR campaign:
The PIN-protected card was not affected by the data breach Target announced in 2013.
This statement is alarming and requiring validation. The PIN numbers apparently were not disclosed during the breach, but online purchases do not require PIN.
The alpha version of new Dark Wallet is now available for download. The Dark Wallet is intended to provide the privacy and anonymity of bitcoin transactions by mixing two (or more in the future) transactions together and obfuscating the acceptance addresses using special techniques.
"We see Bitcoin fundamentally as a new tool of business and trade in the free economy, more than a mere payments innovation. We have made a wallet that will make use of new mechanics to better preserve the financial privacy and freedom of users."
