Middleware Library for Android
The EBizCharge Middleware library allows developers to process EMV, contactless and swiped transactions on the EBizCharge gateway. The library handles all communication between the hardware and gateway. This allows developers to create rich mobile payment applications without the hassle and expense of EMV certification.
The library supports Android 4.0+.
