GlobalPlatform Mobile

Dangerous Things

About this app

GlobalPlatform Mobile manages the applets on JavaCard smart cards and NFC implants from your phone, including Dangerous Things flexSecure and other GlobalPlatform cards. Hold your card to the back of your phone to see what it is, what is installed on it, and how much room is left, then add or remove applets without a computer or a desktop reader.

READ YOUR CARD
• Identify the chip, its GlobalPlatform version and its manufacturing data (CPLC)
• See free storage and memory, measured against a bare card of the same chip
• View the card's keysets, historical bytes and raw tag data

UNLOCK AND MANAGE
• Open a secure channel with your card key, using SCP02 or SCP03
• List every applet on the card by name and version, with the AIDs behind a tap
• Remove applets you no longer need
• Change your card's key

INSTALL APPLETS
• Install from Dangerous Things' open-source applet releases, including NDEF, VivoKey OTP, YubiKey HMAC, U2F, SmartPGP, Satochip, SeedKeeper and JavaCard Memory
• Or install your own CAP file straight from your phone
• Checks free space before it starts and shows install progress block by block
• If the card slips out of range mid-install, the App cleans up what the interrupted attempt left behind and starts again on the next tap
