# Test cards

Integration development runs against the wallee test environment, which accepts cards from the following worldwide brands:

* Visa
* Visa Debit
* Mastercard
* Mastercard Debit

Any card of these brands can be used — including real ones — but we recommend the dedicated test cards provided through this Android app on Google Play:

[VMCP - VISA](https://play.google.com/store/apps/details?id=com.visa.app.chipvmcp)

To test how your integration handles specific outcomes, send a transaction with an amount of `42.xx`, where `xx` is the desired ISO response code. For example, `42.05` triggers response code `05` (Do not honor).
