Are phone/mobile-devices secure for payment transactions?

Your phone/mobile-device which will interface with Cube is just used as a conduit to route the payment data and no data/information is ever stored on the phone/mobile device. Also, all data traffic is encrypted to industry standards. In addition, the Cube itself was developed based on (and has been tested) to Europay, MasterCard, & Visa (EMV) standards and is EMV compliant, and we are always working to improve our product and keep it compliant to industry standards.
