Anyone who actually uses AirDrop never leaves it on continuously with access to "everybody". I bet everyone who got an unsolicited AirDrop bomb didn't even know what AirDrop was.
This. I’d bet most people, in particular Chinese users, don’t even know Apple device can share files in between.

Isn't Airdrop just bluetooth sharing like it was on the Nokia phones days?

Plus, why use Airdrop when the internet is so fast today you can send the images over any IMs or email

Daft question but are you in your contacts?
How can I add my computer to contacts? It doesn't have email or cellphone

Airdrop uses BT to setup a peer to peer wifi connection between the devices.

In my experience it is much faster than uploading the files to the Internet.

I’m actually surprised at the number of people that purposely leave airdrop set to everyone... it would also use more battery even if it’s a small amount

No. It uses a combination of bluetooth and its own local Wifi network. It doesn't require any cellular or existing Wifi networks and you can send huge files like video. Was incredibly useful when traveling overseas where connectivity was spotty and I wanted to share files with others. I can also send/receive a large amount of pictures at their full size and resolution using AirDrop.

I don’t know why, but I have it set to everyone cause whenever I select “contacts only” it never consistently sees my devices.
Me too. It's inconsistent when involving my mac. I rarely have an issue between iOS devices but my mac frequently doesn't play nice unless both devises are set to "everyone." Annoying.

Short answer:

It uses the iCloud settings on the device and creates an ID based on email addresses and phone numbers associated with the user’s Apple ID.

Long answer:

From page 45-46 of Apple iOS Security White paper

“When a user signs in to the iCloud service, a 2048-bit RSA identity is stored on the device. Then, when the user enables AirDrop, an AirDrop short identity hash is created based on the email addresses and phone numbers associated with the user’s Apple ID.”

“When a user chooses AirDrop as the method for sharing an item, the sending device emits an AirDrop signal over Bluetooth Low Energy that includes the user’s AirDrop short identity hash. Other devices that are awake, in close proximity, and have AirDrop turned on detect the signal and respond using
peer-to-peer Wi-Fi, so that the sending device can discover the identity of
any responding devices”

“AirDrop is set to share with Contacts Only by default. Users can also choose
to use AirDrop to share with everyone, or turn off the feature entirely. In Contacts Only mode, the received AirDrop short identity hash is compared
with hashes of people in the receiving device’s Contacts app. If a match is found, the receiving device responds over peer-to-peer Wi-Fi with its identity information. The sending device then initiates an AirDrop connection using peer-to-peer Wi-Fi, and using this connection the sending device sends a long identity hash to the receiving device. If the long identity hash matches a hash for a known person in the receiver’s Contacts, then the receiver responds with its long identity hashes. Then the recipient’s first name and photo (if present
in Contacts) are displayed in the sender’s AirDrop share sheet.”

Your computer doesn’t have email? What kind of a dark age is it from? If it doesn’t have email it probably doesn’t support airdrop

Internet is not fast. It is slow af. And sending files through IM or email is just cumbersome.

Your computer will automatically become your contacts when you login to the same Apple ID you used on your iPhone and/or iPad. Though I wonder what you mean by saying “not having an email”.

hmmm.. interesting, I didn't know you can have Wifi connection to 2 devices, I never heard of that. I always imagined to have a Wifi network you need a "router AP"

When I add a person to my "contacts" I give him a name and a cellphone number and I can add his email. How can I add my MBP as a contact? It doesn't have a cellphone number and it has no "contact email" its a machine. Like a tv or a stereo, they don't have emails to contact them.

I am not sure how fast is your internet, but anything LTE should reach between 10-15Mbps at least, which is fast enough to transfer most documents. This should be enough to download 1GB file in 15min. Unless you are sending over 4K videos, which maybe you should use wired connection.

I have the same problem as the guy below me when I use airdrop
