In January 2016 I started a study of each byte contained in a smart card ATR. See "ATR list study".
My goal was to publish one new article every week. So with 19 bytes that was a job for 5 months. But it took me more than 4 years! I imagine it is because of some lack of time and/or motivation.
My first article was about the ATR list growth. In January 2016 I had 2098 ATRs in the list. Now I have 3316 ATRs in the list and the number is still growing.
The red line indicates the position in January 2016.
New ATRs only
For the last 4 years it is y = 9.381x10-6 x - 2409.7
The growth is now 48% faster than before. Woah!
I guess that is because it is very simple to submit a new ATR using the web interface at https://smartcard-atr.apdu.fr/. Before I create this service, in 2010, you had to send me a new ATR by email. Now you just (mostly) click on a button.
No, I will not re-compute all the statistics with the new, more complete, ATR list.
