No—remove an RFID-blocking card or sleeve before placing your phone on a wireless charger. Qi guidance describes receiver designs that detect RFID or NFC cards in the charging area and stop power transfer, while conductive materials in the charging field can heat. That does not mean every phone detects every card or that every sleeve behaves the same way; the safer choice is to keep the card out of the charging area.
Why an RFID-blocking card can interfere with wireless charging
Wireless charging transfers power through an alternating magnetic field. The Wireless Power Consortium (WPC) explains that conductive objects in this field can develop eddy currents that heat them. Its Qi 1.3 introduction gives coins, keys, and paper clips as examples of foreign objects, and notes that metallic layers in some phone cases can affect or prevent power transfer. Read the WPC’s Qi 1.3 introduction.

An RFID-blocking card or sleeve is not automatically safe to leave in the charging area. Its construction, the phone, and the charger can all matter. The available guidance does not establish how any particular card-and-device combination will behave, and no specific combination is assessed here.
What Qi guidance says about RFID and NFC card detection
The WPC’s informative Qi 1.3 guidance describes a receiver implementation that can use an NFC transceiver to detect an RFID tag or NFC card within the power-transfer area. In the described procedure, the receiver pauses power and checks for a card; if it detects one, the transmitter removes power. If it does not detect one, transfer can proceed under the specification. See the WPC’s Qi 1.3 NFC/RFID card-protection guidance.

This is guidance for a receiver implementation, not proof that every consumer phone or charger uses this protection or detects every RFID-blocking card. Do not treat a charger continuing to operate as confirmation that a card is safe to leave between the phone and charger.
What to do when charging your phone
- Remove the RFID-blocking card or sleeve from between the phone and charger.
- Place the phone directly on the charging surface, following the charger maker’s positioning instructions.
- Carry the card separately while the phone charges.
If you are choosing a charger, check whether the exact product appears in the WPC’s Qi Certified Product database. Certification lookup can help verify a certification claim; it does not establish that a card can safely remain in the charging area.

Does the Qi specification version change the advice?
The WPC’s version-history page, checked on October 7, 2026, listed Qi 2.2.1 as available to WPC members and Qi 2.1 as the latest public download; the page also listed Qi 2.2 in April 2025 and Qi 2.3 in December 2025. Check the WPC specification history for updates. The card-detection and conductive-object guidance cited above is from Qi 1.3 and should not be generalized into a claim about every device or later implementation.
