PayPal Mobile

In 2006, PayPal launched PayPal mobile, a pre-iPhone mobile payment system that relied on text messages instead of apps. Though PayPal eventually changed course, its current point of sale system mimics the old one in a very important way: it does not require any special handsets or apps. (Image: ThinkStock)

PayPal App

Upon Apple's 2008 launch of its app store on the iPhone 3G, PayPal created its own app, leading to a significant boost in payment volume from mobile devices. (Image: ShutterStock)

Bump

In 2010, PayPal added 'Bump' software to allow users to move money by tapping phones. This may seem like a step toward using near-field communication chips for payments, but it was short-lived. PayPal removed Bump in an early 2012 update to its iPhone app. (Image: ShutterStock)

Bling Nation

One of PayPal's earlier attempts at point of sale payments involved a partnership with the mobile payment company Bling Nation. This presumably hit a wall when Bling Nation shut down the following year.

Here
