There is that old saying of putting all of your eggs in basket, which warns you that if you drop it, you will lose all of your eggs! In the case of the Echo card, this does not seem to be the case, in fact with so many cards available to consumers; this could be the way to go by storing all of your cards on a mobile app allowing you to safely use them as when required without physically carrying them around, sounds interesting enough.
This is how the Echo card works and why it is good for you;
Echo has a miniaturized computer inside of it that mimics ordinary cards and syncs with your mobile phone. Our mobile app enables you to convert Echo into the card of your choice with the tap of your phone. Once you select a card for echo to mimic, you can swipe Echo as you would any other card.
