Supports the Google Android ADK, supporting Android phone: G1, Nexus One, Nexus S, Motorola Droid X. For a successful communication to happen using USB protocol, you need at least one of the device to be the host, which means that you cannot connect two keyboards together and expect them to communicate with each other. When you connect any USB device like a mouse or a keyboard to your computer, your computer acts as the host and controls (or polls) the client device (keyboard or mouse or even an Arduino). The Host device controls the peripheral device and also provides power to it. One is called the host (or server) and the other one is called peripheral (client). Before using that, first of all, you should know, what is a USB Host shield? The USB protocol defines two types of devices. They are large no of USB Host shield which is available in the market but the only problem is that you have to choose the right host shield. USB Host shield adds USB Host capabilities to the Arduino board. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play! Using Arduino Compatible USB HOST function, let your Arduino communicate with other USB devices, and supports USB HUB function. If ( ! mfrc522.The Arduino Compatible USB Host Shield is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analogue circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0. it is compatible with more Arduinos – not only UNO and Duemilanove but also Mega and Mega 2560 work with a Standard variant of this shield out of the box.

So was I exactly need is grab the key’(s) from the keyboard until e.g.
Watt also works is the USBHIDbootKbd from the examples of the USB_Host_Shield_Library_2.0. So the code for the rfid writer is done, and works well - but only over the serial monitor (osx) / putty(win10). Connect a Keyboard over USB → USB Host Shield → Grab the pushed key (char) from the keyboard and write them to the rfid writer.
