| My bank sends me an alert when my card is used to make a transaction - handy for spotting fraud. I get an alert when a payment comes it - handy for knowing if a client has paid. I can quickly check my balance - handy for knowing if I can afford another round of drinks. I can repay a friend in two taps - handy if they've paid for dinner. Is anything essential? No. Is it something people use multiple times per day? Yes! |
