Today, with global IT outages, payment systems have been down, so you'd think that cash is king, right? 💷 I went in my local GAIL's Bakery store this morning, happy that I had a ten pound note in my pocket just in case the card payments system was down. But the store wasn't taking card payments or cash! I assume this is because the POS system that tracks all payments was down, and stores could not transact outside of this. Payments could still be made via the GAIL's Bakery app though. (The line between card present and card not present payments continues to blur.) This got me thinking that, as well as having a backup payment provider, in order to ensure resiliency businesses may wish to check what operating system their POS system uses. Most payment outages tend to be further down the chain, at the payment provider level, and not impacting the POS system itself - so in such cases POS systems can often still take payments offline until the payments system comes back online. Today's issue has been due to Crowdstrike, but it has only impacted Microsoft - any systems running Linux or on Apple have been fine. When thinking about resiliency in payments will we see a bigger focus on running across two different operating systems? To be so reliant on one option, that you can't even accept cash payments is a big risk to take. Businesses need to avoid the possibility of any single point of failure. Especially when it comes to payments, where making sales happen is the lifeblood of what the industry exists for.
