As Kara only maintained the machine function, he
didn’t have direct access to the cash box where
the coins were collected after customers had fed
them to purchase LRT tickets.
He removed the face plate from the ticket
machines, which as a repairman would raise no
suspicion
His job would have included duties like resetting the machine if it locked up, removing jams for receipts and ticket printers, loading new thermal paper and cardstock for printed receipts and tickets, etc. Things you would expect someone dressed in company maintenance attire to be doing.
Ultimately what I think happened is that, behind the faceplate, the opening for the coin box is larger than the coin slot on the faceplate, possibly for tolerance reasons to ensure that a coin passing through the faceplate always lands into the coin box. This gap was enough to get an antenna down into with a magnet attached to the end.

The coin slot is in the top right.
