Digital DNA exists in many things. You can use the scanner on your Digivice to find DNA, DigiCores, Soul Cores, and Programs all over the place.

Scanning from Enemies

A defeated enemy can become scannable and leave any of the above in their wake. Once the enemy loses that scannability or becomes a Digitama, the leftover DNA vanishes.

Scanning from Scanner Points

The Digivice can detect scanning points that are located throughout the planet. If one is around, a circle of digital code will appear. You're more likely to find larger amounts with better supply outside of the city.

Scanning from Objects

Like with Scanner Points, the Digivice will make any scannable data have a shine to them. A smaller circle of digital code will appear. Unlike Scanner Points, the data in objects are one serving, first come first serve.
