Apple requires that eKeypad licenses be associated with your Apple ID. This means that you will need a one license for each Apple ID used on your devices. Licenses for eKeypad are valid for both the iPhone or iPad.
This means that if you have three mobile devices that are managed by a single Apple ID you will only need a single license for all three devices.
However, if your three mobile device are each manage by a different Apple ID then you will need three licenses. One for each Apple ID.
Apple does not allow for volume discounts. Apple also does not allow licenses to be transfered from one Apple ID to another.
If you need a large number of licenses contact us. A custom application may be more economical.
