A few months ago, a small VR game named “Rec Room” was permanently shut down. The game functioned more as a social hub for children than an actual game, so I wasn’t terribly sad to see it go.
But one feature in it genuinely moved me: adding a friend.
In Rec Room, when you met a person and you wanted to add each other to your friend list, all you did was shake hands.
And I don’t mean click a button labeled “shake hands,” I mean literally grab that person’s virtual floating hand, squeeze your controller, and shake, like in real life.
It’s a small gesture, but it was incredibly impactful. Knowing that someone, somewhere across the planet, was making the same physical gesture as you at the same moment felt “real” in a way that is very rare in VR.
Bump beat Tap to Share to this feeling by 15 years
It ran on a fist bump, not a radio signal
The last time I felt something like that was all the way back in the early 2010s, with a little app named “Bump.”
Like the handshake in Rec Room, the idea was almost trivial. If you want to exchange information or files with another person, you fist bump each other while holding the phone in your hand, and the magic happened automatically.
Like in Rec Room, this gesture felt more real than sending a file by choosing it from a menu and pressing Send.
It added a physical layer to the interaction, and for exchanging contacts, this gesture made a lot of sense.
Fifteen years later, we now have many ways of doing the same thing: sharing contacts and files between phones, some of them even very similar to what Bump did back then.
But I’d argue none of them ever had that same “this feels right” feeling I got from the original Bump, or from shaking a virtual hand in Rec Room.
Tap to Share is the closest thing we have to that feeling today. You point two phones at each other, and the contacts or files move between devices. It works.
Yet it also shines a light on what the developers failed to understand about what made bumping so much better, and it’s not only the social gesture. The technology matters just as much.
When Bump came out, smartphones were making their first baby steps. The technology was more limited than it is today.
If you want to transfer files between two phones today, the best and most secure way is with NFC. Back then, that wasn’t an option.
Bump never actually connected your two phones
No Bluetooth, no NFC, just a very patient server
The way Bump worked is ridiculous by today’s standards. You would think the bump somehow connected the two phones, perhaps via Bluetooth or some other kind of wireless connection, but in reality it was more complicated.
As you and your friend bumped phones, the accelerometer registered the exact moment of impact, and your phone’s rough location, off cell towers or Wi-Fi, nothing GPS-precise, and then it sent those to Bump’s servers over your regular data connection.
That’s where the real trick happened. Somewhere in a data center, an algorithm watched every bump happening on Earth at that moment, looking for two signatures that matched: same rough spot, same instant.
When it found your pair, it asked both phones to confirm, and only then did the file move, down from the server to the other phone, also over the internet.
The two phones in your hands never spoke to each other. No Bluetooth pairing, no NFC handshake, nothing local. Every bump was shipped to a server somewhere and mailed back.
Sharing a contact in 2026 is straightforward. You and your friend hold the phones close to each other, they connect via a secure short-range connection, and the transfer happens directly between the two phones.
Nothing is uploaded to any cloud, and no algorithm has to guess who’s sending what to whom.
This makes more sense from a technical point of view, but I can’t help feeling that it lacks the social element that was so clear with Bump. That physical aspect of fist-bumping another person felt like a social interaction.
Tap to Share involves two people standing in front of each other, holding their phones like little prayer books, trying to get the two phones to play nice.
NFC is more secure, but it’s also less reliable. Any small movement of the phones can break the connection, and the process needs to restart.
I’m not saying Bump was better. I’m saying it “felt” better. It felt natural. And I believe it will feel even more natural now, in this post-COVID world, where the fist-bump seems to have replaced the handshake in most social situations I have been in lately.
Google bought Bump to build this, then killed it anyway
I don’t want Bump back; I want the gesture
So what happened to Bump? Like many successful apps, it was bought by Google and then shut down four months later, on January 31, 2014.
Here’s the actual loss. Tap to Share, and NameDrop and everything in that family are good. I use them, I like them, I don’t want them gone.
But what we have today isn’t what was killed in 2014. Bump worked at almost any angle because it ran on motion, not radio. You could hit fists sideways, low, off-center, half-drunk at a conference, and it still caught the bump.
NFC needs the antennas close and roughly aligned, and Android’s antenna isn’t in the same spot on every phone the way Apple’s is.
The old, dead method was more forgiving than the one that replaced it. We didn’t get the gesture back. We got a more careful version of the outcome.
I’m not saying I want the old Bump back. The last thing I need is another server holding my personal files. What I want back is the gesture.
A social gesture that means something to two people sharing a contact, a photo, or whatever else makes them connect in that moment. It’s 2026; the technology is there, someone needs to make it.
It’s a small gesture, but it’s incredibly impactful.
