Cardless TI: How NFC replaces the eHealth card terminal

Abstract illustration of an NFC interaction between a smartphone and an eGK card.

Every German TI setup today carries the same assumption: somewhere in the practice sits an eHealth card terminal, cabled to a connector, waiting for the patient's elektronische Gesundheitskarte (eGK) to be inserted. It's a reliable piece of hardware — and it's also the reason TI stops at the front desk.

Cardless TI removes the assumption. The eGK is read via NFC, on a smartphone, using the chip that ships in every modern Android and iPhone. No card terminal, no cable, no dedicated slot.

What changes

The mechanics are simple: the patient holds their eGK to the back of a phone; the NFC chip reads the card in the same way an eHealth card terminal would; the cryptographic handshake with the TI happens over the phone's network connection.

What this unlocks is anything but simple:

Why verkstedt is building this

Cardless TI is one of verkstedt's pioneer products and the headline showcase of our joint appearance with gematik at DMEA 2026. It builds on the same cardlink infrastructure we've been operating for gedisa in production — the card-reading pipeline is not new; what's new is removing the last piece of dedicated hardware from the chain.

TI has been mobile in ambition for years. Cardless TI is what mobile actually looks like.
