What is the difference between ISO 14443-3 and ISO 7816-4 APDUs?
I'm asking this because seems some cards use former to communicate with reader, some latter.
I'm confused with this, would like to get a good understanding about this.
For example, I think Mifare Classic uses ISO 14443-3. But what confused me here is that
when I wrote application to communicate with Mifare classic, I *was* sending APDUs to it.
