Decrypt track2 data

We have developed a gift card app.

When we define the bin range, the track2data comes back encrypted.

I checked the sample code as suggested in this Poynt Form Post but need more direction.

I have the private and public keys.


I was able to resolve this issue by working with the Poynt team and adding our BIN ranges to a preapproved list beyond the ones you code into the app as described into the SampleApplication
