Put your PolyU staff/student ID card away from smartphones while using wireless charger

Staff and student ID card has a built-in chip set to support fast reading of encrypted information stored on card from device using Near Field Communication protocol.

 

 

Wireless charging has become one of the standard features on smartphones as it provides user convenience to charge their smart devices without the need of plugging in a cable. The latest wireless charging technology can deliver up to 15W of power to achieve fast charging. However, the technology of wireless charging is based on electric induction which means the electric power can also be induced to your smart cards and credit cards, causing damage to the chips embedded in them and leading to card malfunction when you use them.

Please remove your staff or student ID card from your smartphone before you place the smartphone on a wireless charger.
