Digital payment firms Javien and Digonex have teamed up to offer clients access to the others e-commerce systems.

The Javien platform lets consumers charge items to their mobile phone bill, landline phone bill or other alternative accounts like PayPal.

Digonex's system allows digital retailers to dynamically change the price of content -- such as music tracks or albums -- based on how much activity any individual item receives.

The deal allows clients of one to take advantage of the capabilities of the other.
