Is it possible to make a wearable travel/credit card?

Question

NFC

I know that now there are all these Android Pay for contactless payment, and it all works even with smart watches. But is it possible to bring the following concept to life, somewhere on aliexpress a similar device is walking around:

• Wearable device, similar to fitness bracelets and smart watches
  
• Ability to switch between operating modes
  
• As operating modes, I mean switching from travel mode to credit card mode, let's say you go to work in the morning, switch to travel mode, get on the bus, apply it there or in the subway. Then you go to the store after work, switch to the card mode and pay for the purchase
