RFID wallets are specially designed to block radio frequency signals. Therefore the Chipolo might not function properly or lose connection sometimes while used in RFID blocking wallets. 

If you specially bought Chipolo for this purpose, please contact our support and we will (within the term of 30 days) refund your order. We can only refund orders directly from our website, otherwise we recommend you to take it back to the seller you bought it from originally.
