Hello,
The readers share similar functionality and the ability to read/ write standard HF tags. And both products can be connected to cell phones, PDAs, handheld computers, laptops and desktops via Bluetooth or USB.
The Padl-R HF reader is specifically designed to be handheld (light weight and ergonomic). It is used predominantly in asset tracking, particularly for high value assets such as equipment and machinery. A key benefit of this reader is the ability to batch log and store tag data without connection to any other device so the user does not have to carry a relatively heavy handheld reader in the field. You simply collect the tag data with the Padl-R reader then download the read information later using a Bluetooth or USB connection. Read range on ISO 15693 tags is 8 – 10 cm. User feedback is via 3 LEDs and a beeper.
The Explore-R HF is a credit card sized desktop reader which is perfect for monitoring work in progress/ personnel or proof of concept applications. It does not support tag logging on the unit and has no real time clock. Read range on ISO 15693 tags is 3-5 cm. User feedback is via 2 LEDs only.
