Weighed down by your wallet? Purse cluttered up with cards? Then perhaps Kerv is the wearable you’ve been waiting for. This smart ring enables people to make payments without a counterpart device, while also functioning as an Oyster card and a repository for emergency and medical info.

The world of finance might be headed towards a cashless future, but cash is still very much king in some parts of the developed world. Many Germans for example, prefer to perform their everyday transactions using cash, perceiving it as a more secure and private way to go about their business.

British charities missed out on £80 million in 2016 due to cash-only donation systems. In an effort to combat this, Barclays has launched donation boxes that accept card-based payments, theorising that a seamless payment system could lead to a spike in random acts of giving.

Cash may be far from dead, but for many, going cashless is becoming an increasingly palatable concept. Although these payment options are nothing new, the way people make transactions is evolving – 47% of Brits carry less than £5 in cash at any one time, while almost three quarters of Brits say they’d use wearables to pay for drinks or transport. And it’s the convenience that’s winning them over – 82% of people say the speed of paying is the biggest plus.
