They should standardize a system where your card issuer can send a simple API call to cancel a subscription.
Log into your bank/card's website, see a list of your subscriptions, click cancel on one and it tells the company to stop charging you instantly.
I feel like with all the money our card issuers are making, they could very easily make better quality-of-life features, but they choose not to.
Of course, that feature would reduce their total fees, but even a feature like getting a digital copy of your receipt sent along with your payment would be amazing. Not by email, but just on your card statement.
Well quite, but that also explains why they're so reluctant to offer any new features until they've been completely overtaken by newer fintech outfits and are noticeably losing customers.
