Tappy NFC Reader

The Tappy family of high-powered external NFC readers support a wide variety of basic and advanced NFC operations, which, in addition to offering superior performance to most Android devices' onboard NFC, can be leveraged to bring NFC capability to devices that do not have an NFC reader built-in.

This app supports connecting to TappyUSB readers via a USB On-The-Go adapter as well as TappyBLE readers using low-energy Bluetooth® wireless technology. It is capable of issuing and understanding a simplified subset of the Tappy's available commands that allows it to be used for many common NFC use cases.

Supported operations include: detecting tags, reading NDEF-encoded data, optional automatic launch of URLs read from tags, encoding text data, encoding URLs, transceiving APDUs to ISO14443-4 tags, locking tags, and reading MIFARE Classic® tags.
