It’d be pretty cool if, on your friends birthday, you sent them money there was an altered notification to them and perhaps a little animation when they open it if you’ve sent them some money for their birthday.
Sort of like a electronic birthday card
Just a small but cool little feature that would be nice to have
If you’re sending the money for that purpose, you already know.
The only person seeing the animation is the person whose birthday it is, so I can’t see how that violates anything.
And you’re assuming any animation is being triggered by the DOB being read from the account details - but it could be by calling the reference “Birthday money” or something like that.
When sending a payment there could be a simple toggle to mark the payment as a gift. This would then trigger the animation/message on the recipients side.
