Please try to provide a more thorough answer: provide links to such SD card readers, post some sample code on how to read/write variables from it, and mention how it is better than EEPROM.

Good suggestion. SD is using a regular SPI interface. So all you need is some logic-level-conversion. Beside that you wire them directly to an Arduino. Just solder some wires to a micro-SD to SD adapter.

+jfpoilpret IMHO SD Card Readers are ubiquitous and shouldn't need examples or citation. The code is dependent on the brand of reader so no point in providing arbitrary code. I did mention how it is better than EEPROM, it isn't too difficult to buy or build.

```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
