FAQs
Why should I buy an eReader?

Unlike phones or tablets, eReaders are designed purely for reading. The e-ink screen is easy on the eyes and perfectly visible under sunlight, the battery lasts for weeks, and the lightweight design makes it convenient to carry anywhere. For avid readers and learners, it’s a healthier and more focused way to enjoy books.

Is Xteink eReader suitable for commuting and travel?

Absolutely. The X3 is about the size and weight of a smartphone, turning your pocket into a portable library. Whether you’re on the subway, at a café, or on a long flight, it transforms idle moments into quality reading time.

Can I use the X3 to copy or simulate NFC cards?

Yes, the X3 supports unencrypted card simulation for legal, personal use only (such as standard personal access badges). Duplicating encrypted cards or using this feature for any illegal purposes is strictly prohibited.

Is my data safe? Where is it processed?

Your privacy is our priority. All data is processed locally on your device. We do not upload, store, or share your personal information on cloud servers, ensuring total privacy and security.

How can I ensure charging safety?

Please use a locally certified, safety-compliant charger to ensure safe charging. Additionally, avoid allowing conductive objects to contact the charging Pogo pins to prevent short circuits.
