Zenst, our product is extremely secure. All card holder information is actually stored in secure memory on the card (Echo) itself, not on the phone or app. By default, Echo locks when out of range of your phone's Bluetooth (and can be unlocked by entering a pin code on echo, enabling you to use Echo without your phone). So, even if you lose Echo or phone, your card info will not be vulnerable to theft.

At least my NFC mobile phone has remote wipe.

Exactly and easier to report stolen as well.
