The SwipeSimple version 3.0 (which accepts both EMV chip cards and swiped cards) works with iOS version 7.0 and higher as well as Android OS version 4.0.3 and higher. If you're using SwipeSimple version 2.1.6 (accepts swiped cards only), it will work with iOS version 6.0 and above as well as Android OS version 4.0.3 and above. You can always test your device by downloading and launching the SwipeSimple app, then entering demo mode and attempting a test transaction.
The reader itself inserts into your device's headphone jack, so many sure your smartphone or tablet is equipped with one of those.
If you are having trouble getting the device to fit into the headphone jack, try removing the case or protective covering from your device.
