## Card ID Logic
To support all kinds of different NFC cards or tags, card IDs are transformed with the following rules (apply to both AIME and CardIO).
* 15693 => Original 8-byte UID
* MIFARE (4-byte UID) => 0xE0 + UID + first 2 bytes of the UID
To support many different NFC cards and tags, card IDs are transformed following these rules.
### AIME
* 15693 => 0x01 + last 7 bytes of UID
* MIFARE (4-byte UID) => 0x01 + 0x01 + UID + first 2 bytes of the UID
* MIFARE (7-byte UID) => 0x01 + UID
* FeliCa => Original IDm
### CardIO
* 15693 => original UID
* MIFARE (4-byte UID) => 0xE0 + 0x04 + UID + first 2 bytes of the UID
* MIFARE (7-byte UID) => 0xE0 + UID
* FeliCa => Original 8-byte IDm
* FeliCa => Original IDm
