Spendwallet

This is a smart electronic wallet. With this you can digitally consolidate the data of up to 20 cards into the device securely and gives an easy access to each of the cards data.
Now this works with card readers easily, it's magnetic flux emulation technology makes the card reader act like a card was swiped through it by generating a magnetic field.
To store your cards data on this device,, all you need to do is syn it with your phone and via the app you can install your data into the spendwallet. It is also rechargeable via USB and has a battery life of 4 weeks per full charge.

This is really innovative for me and would solve the problem of carrying about multiple cards. Now all you need to do is tap to pay, no more swiping.
