GMMC Pocket NFC Reader/Writer
13.56 MHz Multi Standard USB NFC Reader/Writer
Manual version 1.2
Introduction
The Pocket NFC reader/ writer is USB connected and powered and operates at 13.56 MHz. The
Pocket NFC reader offers different tag related functionality and USB communication modes.
If the tag is out of communication distance or if the communication is disturbed by harsh
environmental noise, the implemented automatic tag detection reestablishes the reader-tag
communication link
Independent from the analog RF circuitry, responsible for RF performance and communication, three
different digital USB host interface configurations are available.

USB VCOM (Virtual COM port) via CDC (communications device class)
USB CCID (chip card interface device) is a USB protocol that allows a smartcard to be
connected to a computer via a card reader.
USB KBD (Keyboard) as part of the USB HID (human interface device class) specification for
computer peripherals. It specifies a device class (a type of computer hardware) for human
interface devices such as keyboards, mice, game controllers…
Basic Reader behavior
Once the reader device is connected and USB power is available the device boots up and switches
the RF field on and starts automatic tag polling. The three board status LEDs (red/green/blue) are
used to indicate different states, depending on the integrated firmware´s function e.g. Power, RF
polling, communication…

cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the Receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
Intended Use
The device is intended to be used directly plugged into e.g. a PC, Laptop, USB bus extender, router
or the likes.
If the device is used with a USB extension cable, it is the responsibility of the user to select a cable
that preserves compliance with the regulations applied. When connecting a USB extension cable, it is
recommended to use one with a ferrite close to the device.
Modification of equipment
Changes or modifications made to this equipment not expressly approved by the party responsible for
compliance may void the FCC authorization to operate this equipment.
Notice
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science
and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following
two conditions:
(1) This device may not cause interference.
(2) This device must accept any interference, including interference that may cause undesired
operation of the device.
Indication
L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR
d’Innovation, Sciences et Développement économique Canada applicables aux appareils radio
exempts de licence. L’exploitation est autorisée aux deux conditions suivantes:
(1) L’appareil ne doit pas produire de brouillage;
(2) L’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible
d’en compromettre le fonctionnement.
