In the digital age, new ways of spending and exchanging money are constantly emerging to suit different needs.
New services like mobile payment systems and e-commerce platforms remove the need for cash or checks, as well as old-fashioned monetary exchanges between friends and family members.
Instead, we can now send or receive payments digitally using credit card information stored on smartphone apps or online profiles. For example, Apple Pay allows users to make purchases with a tap of their iPhone instead of a physical wallet full of cash.
Likewise, Venmo makes transferring small amounts of money between friends easy by sending and receiving digital payments through their mobile app. But what if there was another way to exchange value online that is more secure than current systems?
