1. Introduction
The RP901 is a Wireless UHF RFID Pocket Reader that uses Bluetooth as the communication interface. It can
quickly connect mobile devices such as computers, mobile phones, tablets, etc. through the HID (Human Interface
Device) interface, without installing additional device drivers, and can complete an array of operations by
integrating its Apps with the Cloud. With a streamlined contemporary styling and a fresh, simple, two color
design, it is ergonomic and easily fits in one hand. With a 1.5 meters Drop‐protection rating, it is also suitable
for outdoorsy use in various harsh environments. The RP901 has an 1100mAh internal battery and 2MB of
internal memory, enough for 10,000 offline scans.
1‐1. Product Features
Light and Easy to Carry
Using Bluetooth as the communication inter
f
ace, the RP901 avoids wiring limitations and enables users to
trans
f
er and sync data without changing their work style. Weighing in at
j
ust 70g, the product is easily held in
one hand and is shaped ergonomically.
Novel Exterior Design
The two‐color exterior design is
f
resh, simple and clean. The plastic shell is curved,
f
ashionably shaped, and in
harmony with mobile phones and tablet usage.
Industry Level Protection
The RP901 is a Wireless UHF RFID Reader
f
eaturing a 1.5 meters drop protection rating. It is suitable
f
or
outdoorsy use in extremely harsh environments.
High Performance Reading
The RP901 can read multiple UHF RFID tags at the same time. The 100 cm Read Distance also enhances its
mobility and practicality.
Excellent Compatibility
Featuring Secure Simple Paring (SSP), the RP901 is compatible with the various mobile phones and tablets
in the market. User simply taps on the screen to connect devices via Bluetooth HID interface while no pin‐code is
required.
Long Battery Life
The 1100mA internal lithium battery powers up to 6,000 scans on a full charge, eliminating the need
f
or
f
requent battery changes, ensuring employee efficiency.
Human Centered Design
Streamlined, simple button and light indicator design saves users
f
rom spending time fumbling. The unique light
indicator and vibrator communicates read status to the user even in noisy surroundings. A detachable hand
strap is also included, so the device may be tied to the waist or hung on the neck, making it easy to reach
f
or
anytime use, and hard to lose.

*Please refer to 5‐9‐2. Beep Time for beep length configuration.
**It can be that an obstacle between RP901 and host device has interfered with the data
transmission, or RP901 is too far away from the host device. To fix this, please get back
in effective transmission range.
