Paypal is taking another step to making your cash easier to access by rolling out a two-click mobile payment system called Mobile Express Checkout, which was rolled out today at a developer conference in San Francisco.

Allowing more access to using Paypal when making online mobile purchases is the major goal here. Mobile Express Checkout users can use the service to stay logged in while using multiple mobile apps, making online shopping less of a hassle.. Web-based stores that accept Paypal will find the system easy to implement into their stores, and merchants may also be able to accept credit cards through Mobile Express Checkout in 2011. The beta has been very successful, with many companies reporting double-digit sales growth since adding the feature.
