How does one acquire these tags? I assume theft, but can they be bought?

[–] tracyspcy@lemmy.ml 2 points 2 weeks ago (1 children)

there are plenty of them on ebay and aliexpress, and they are pretty affordable

[–] CameronDev@programming.dev 2 points 2 weeks ago (1 children)

Cool. Dunno about affordable, I'm seeing around 25AUD, which seems a bit pricy? Maybe supermarkets get heavy bulk discounts?

you can also look for a used ones, they should be cheaper. Also they are selling in bulks like 5, 10 tags, then price is better.

ps I also know cases, then people just asked in local store if they have broken or unused one and getting them for free. Maybe some of them are repairable.

Used does bring up the "theft" concern, but I'll have a look.

I have a friend who found one near a shop dumpster, so maybe I'll just have to keep an eye out :D

Haha yeah for sure
