Relay: Relays NFC traffic between two devices using a server. One device operates as a "reader" reading an NFC tag, the other device emulates an NFC tag using the Host Card Emulation .13. First of all you have to get permission in AndroidManifest.xml file for NFC. The permissions are: . . The Activity which will perform NFC Read/write .

GnuPG supports the use of hardware security tokens that come as smartcards (or USB devices that support this mode). The tokens are minicomputers that can hold the secret key material and perform crypto operations.The gpg-card is used to administrate smart cards and USB tokens. It provides a superset of features from gpg --card-edit an can be considered a frontend to scdaemon which is a daemon started by gpg-agent to handle smart cards. If gpg-card is invoked without commands an interactive mode is used.The OpenPGP Card is an ISO/IEC 7816-4/-8 compatible smart card implementation that is integrated with many GnuPG functions. Using this smart card, various cryptographic tasks (encryption, decryption, digital signing/verification, authentication etc.) can be performed.
GnuPG comes with a tool to administrate smart cards and USB tokens. This tool is an enhanced version of the --edit-key command available with gpg. Smart cards let you store the private key on a tamper resistant piece of hardware instead of scattered across various computers (where it can be accessed by other users of the machine, malicious software, etc).
What benefits do smart cards capable of storing private keys, and devices like the YubiKey Neo (which seems to be a smart card + usb reader in a single dongle) offer above storing private keys on a plain-old usb thumb drive? Does the smart card ever "reveal" the private key to applications like SSH or GPG?First you need an OpenPGP compatible smart card which can, for example, be obtained by becoming a fellow of the Free Software Foundation Europe. Card readers (NOT those used for flash memory cards) can be obtained from computer stores (e.g. https://www.floss-shop.de/en/security-privacy/). This setup makes use of a Smartcard paired with a small form-factor Smartcard reader to effectively create an OpenPGP USB “token.” (Note: This reader does NOT have an external PIN pad for secure PIN entry, so if that’s a concern for .The OpenPGP smartcard was conceived by g10 Code, the main group behind GnuPG development. It is worldwide and primarily distributed by the German company Floss Shop (former Kernel Concepts). The Free Software Foundation Europe (FSFE) donated a customized version of the OpenPGP smartcard to all new members, calling it the Fellowship crypto card.
The Kernel Concepts cards work fine and are by far the easiest option. There are several PGP apps you can load onto Java-based smart cards, including Yubikey's own app. This requires that you buy the blank , compatible Java card and go through the process of programming it.
