DL Signer Card 30M48CR – Digital Signature Tool
Dual interface 48k EEPROM contact + contactless card

DL Signer cards are a digital signature tool  intended for the digital signing of data and documents using RSA or ECDSA asymmetric cryptographic algorithms.

DL Signer Card 30M48CR is a dual interface card (contact and contactless) based upon JC30M48CR java card with 48k EEPROM.

For eSigning, this card implements Digital Logic’s Java Applet for Digital Signing in accordance with Java Card 3.0.4 classic edition and GlobalPlatform Card Specification 2.1.1.

Java Card maintains compatibility with the third-party applets as well as all existing smart card infrastructures. It facilitates the integration of multiple sourcing components within the smart card solutions.
