My guess is IC is Mifare Classic
As mentioned by Amal above
I see the frequently, especially when looking at chinese locks and cards.
In fact, it makes me happy, because I know it is compatiable.
Whenever I travel, that is one of the first things i’ll do.
- Handed my room card
- Out comes my phone or Flipper
- TagInfo of NFC
Cross fingers a Mifare Classic
I would have high hopes for your “IC” card
