It seems we can’t go more than a day or so without another e-wallet report popping up. The latest comes from Samsung and Visa. The companies announced they will launch an Olympics-branded phone that will bring mobile payments based on near-field communications technology to the 2012 London Olympics.

According to a press release, the “Samsung Olympic and Paralympic Games mobile handset” will need a Visa-enabled SIM card to make contactless payments. Users can pay by booting up the Visa mobile contactless application, selecting the pay option and then holding the phone up to a receiver. The release said there are already more than 60,000 locations in London that accept contactless payments.

ReadWriteWeb reached out to Samsung to see which handset will be getting the Olympic treatment, but the phone company said it’s not ready to tell quite yet.

Amazon is also said to be looking into launching a mobile payments program. Friday morning, Bloomberg  cited two people with knowledge of the project who said that the company will decide whether to launch the program“the next three to five months.”

The online retailer’s program would let customers to pay for Amazon goods in actual stores using their mobile phones. Amazon may also launch a marketing service using the technology. If, for example, a customer can’t get the right size of a product in a store, they can just wave their phone over a tag to find what they want on
