Digi-Modify

Digi-Modify (Card Slash) is the term used in Digimon Tamers to refer to the act of modifying a partner Digimon's capabilities through the use of the Japanese Digital Monster Card Game.

Concept
In Digimon Tamers, Digimon normally have to absorb data to get stronger. A Digimon partnered with Tamers on the other hand has the capability to temporarily increase its power using cards scanned through the Tamer's D-Power. This act looks like the Tamer is "slashing" their card through the Digivice, hence the Japanese term "Card Slash".

Blue Card
The Blue Card is unique in the sense that it is not exactly a card but an algorithm that was created by Shibumi. When used, the Blue Card can have many effects.

The swipe of a Blue Card into a card scanner or a similar card reading device can transform the device into a D-Power. Swiping it through a D-Power can instead release 's powers and allow Matrix Digivolution to Ultimate. It can also allow the materialization of digital lifeforms from the Digital World into the Real World.

When used, the Tamer calls it the "Matrix Digivolution" (Matrix Evolution) card.
