Isn't this built in to either iOS or Android [or was in the past]? I'm pretty sure there was some way of exchanging contact info via Bluetooth or BLE, involving tapping phones together. Or am I misremembering? I've never used the feature myself [if it exists outside of my fevered imagination] EDIT: Just checked on my Android phone. In the contacts app, I can bring up someone's contact info > click Details icon > then Share > choose VCF or text > and then, choose Bluetooth as the sharing option and send it to another device. Yes, it's a bit of a faff, but it is there and is built-in.
