MODE OF OPERATION

OPERATING MODE

In order to start operating TWN3 Mini Reader MIFARE NFC, it simply has to be connected directly to a host device.

POWER UP

In case of an external power supply unit is used, the following requirements must be satisfied:

Limited power source according to the safety norms listed in the respective declaration(s) of conformity
Short-circuit current < 8 A

ENUMERATION

This is only applicable for the USB version: Once the device has been powered up, it is waiting for completion of the enumeration by the USB host. As long as the device is not enumerated, it is entering a minimum power consumption mode.

INITIALIZATION

After powering up and enumeration (in USB mode), the device is turning on the built-in transponder-reader logic. Some RFID reader modules need some kind of initialization, which is performed in this step.

NORMAL OPERATION

As soon as the reader module has completed the initialization, it is entering normal operation. During normal operation, the reader module is searching for a transponder continuously.

DETECTION OF A TRANSPONDER

If a transponder is detected by the reader module, the following actions are performed:

Send the ID to the host. By default, the USB device sends by emulating keystrokes of a keyboard.

Within the two seconds timeout, the transponder, which just has been recognized, will not be accepted again. This prevents the reader module from sending identical IDs more than one time to the host.
If during the two seconds timeout a different transponder is detected, the complete sequence restarts immediately.

SUSPEND MODE

The USB version of the reader module supports the USB suspend mode. If the USB host is signaling suspension via the USB bus, the reader module is turning off most of its power-consuming peripherals. During this operation mode, no detection of transponders is possible. Once the host is resuming to normal operation mode, this is also signaled via the USB bus. Therefore, the reader module will resume normal operation too.

COMPLIANCE STATEMENTS

EU

TWN3 Mini Reader MIFARE NFC is in compliance with the EU directives and regulations as listed in the respective declaration of conformity.

RF EXPOSURE COMPLIANCE

RF exposure statement (mobile and fixed devices)
This device complies with the RF exposure requirements for mobile and fixed devices. However, the device shall be used in such a manner that the potential for human contact during normal operation is minimized.
