I have a prediction: Airlines won't ackowlege that personal trackers as an effective means to track luggage becuase they're trying to figure out how to force you to buy their own trackers.
Frankly I’m trying to figure out how a system that even allows for luggage to be lost without any accountability is allowed to exist in two thousand twenty fucking three
Lobbying is easy: "we'll give you free first class flights if you don't pass any laws against us"
Cause somehow we've been convinced that if something somehow works once, in one specific scenario - then it must in its entirety be ok for all eternity
(as long as it makes money of course lol)
Easy: doing so would cost too much money, for not enough profit gain.
Aka, there isn't enough competition between airlines
This is a pile of horseshit right here.
Service in airlines was at its absolute worst when competition was at its tightest. It's shit now, yes, but during the height of deregulation and "innovations" like the cattle car airlines it was far, far, far worse.
I'm still trying to figure out why they don't already use trackers. RFID tags are dirt cheap and it's 20 years old technology. They already have a process where they add barcode stickers at checkin, slap some RFID in there too.
They certainly can and do use a tracking system.
I get notifications from Delta every time my bag moves once it's checked in - loaded, unloaded, what pickup.
There's nothing really wrong with barcodes. NFC/RFID would be a logical upgrade though, and just has to integrate into the existing system.
Still an additional cost they’d rather avoid.
Surprised they don’t offer it as a $20 up charge…
You have to change a lot of equipment to make it useful. Most major airports have very complicated machinery that uses the barcodes, which feeds into the baggage handlers. I don't know how they fix that machinery to make BLE worth it.
They don't have to convert their entire luggage handling setup to RFID, just use it to augment their lost luggage detection.
Add RFID readers at strategic points and feed their data into a computer, which in turn feeds it to a replicated database. When a piece of luggage is lost look in that database to see where's the last RFID blip. Also very easy to let the customer see their luggage positions on a website.
I think you mean BLE. As far as I understand it, RFID doesn't have any particular advantage over barcodes for tracking luggage.
Barcodes need line of sight with scanners and close range. RFID detectors can sense tags at larger distances and just based on general proximity.
BLE is also an option, comparison to RFID would depend on setup particularities. RFID would be the more natural choice for throwaway, recyclable stickers that just need to store a short "dumb" ID.
RFID is easier to read, so you could set up scanners at more places. Also easier to walk around looking for a bag and know that it's somewhere in this pile.
I could see airlines banning the use of these before that ever happens. If I’m not mistaken one or two already have.
I don't know how air tags even work. So they have a cellular connection or something? How are they able to be tracked?
They use a newer low-voltage Bluetooth radio that has a very limited range. When another Apple device like an iPhone, iPad, laptop, etc. is in range then that device will ping Apples servers with an updated location for the air tag in question.
Crowd sourcing. AirTags and other similar trackers emit weak, short range Bluetooth beacons that any iPhone can quietly detect and report along with where they were when the beacon was seen. There are privacy implications for sure, but it works.
AirTags actually use an encryption scheme. The AirTag will broadcast a public key. The private key is stored in your iPhone and iCloud keyring. Once your phone fetches the location reports from apple's online service it can decrypt the actual location of the AirTag.
They use a combination of Bluetooth and nfc and maybe some wideband spec (though I think the wide and stuff is just for when you go in searching) . Basically anytime it’s near another iPhone, the iPhone picks up the tag ID and sends it in.
If it detects a lot of checkins to a phone that isn’t on the same Apple ID, the AirTag will make noise (as an anti-stalking measure)
I believe a recent patch also allows android to report in status, or maybe that’s coming but still in the works. Not sure.
Android won't track airtags, but will allow 3rd party tags to work via "find my phone" (becoming "find my device"). They have coordinated with Apple however for anti stalking measures. Both can detect longer term presence of each other's tags, and sound a warning. Apparently they have delayed the release, to allow apple to implement the protocols properly before they do.
Google's are simple BLE beacons. They ping out periodically, and any android phones nearby note and report its existence and strength (along with their location).
They use a low power Bluetooth (BLE) technology to send beacons that any iPhone can pick up and relay to Apple. They only work because many people have iPhones.
They're Bluetooth beacons. Basically they transmit a very low power signal that any nearby iPhone (I think Android phones do it too now, but I'm not certain) can pick up. When a phone receives the signal it sends the information about the tag and the phone's current location to the central server. You can then track the tag from there.
