Possible to Read/Write FeliCa Card Device by Using iOS Device

By using Bluetooth Low Energy to connect this device with iPhone, iPad, or iPod touch (iOS device), various types of FeliCa card devices can be read/written by applications on the iOS device. As this product and the iOS device are connected via Bluetooth, remote communication is possible within the effective range*1.

*1 Communication is possible within an effective range of approximately 10 meters. This range, however, varies depending on the presence of obstacles (such as a person, metal objects, or walls) and the condition of the radio wave.

Conveniently Portable

The product has a simple design and is only 5.5 mm thick, with the same width and height as an IC card. It can be carried around easily by using the card holder provided with the main unit, together with a commercially available neck strap.

Long-Lasting Operation Thanks to Low Power Consumption Design

The product contains a Lithium-ion battery, so repetitive charging is possible using the enclosed USB cable. Thanks to the optimized design for power consumption control, this compact device can be used for approximately one month*2 after a full battery charge.

*2 Battery duration when the device is used for value top-up once a day and the remaining value-balance is checked once a day after a full charge.
