At face value, the Fuze Card seems like a wonderful tool for cutting card clutter.
Pity it seems set for spectacular failure.
There’s enough historic data to show that there’s no reason for the Fuze to work.
By all means, support them. But do it to receive a keepsake, not a usable product.
There are plenty of mobile payment options. You don’t need another piece of hardware to make payments. A mobile phone loaded with the right app is a powerful payment system.
Google and Apple (to name but two) both have amazing payment options. You don’t need another card.
