The adhesive is made to remain sticky and can be transferred (though we don’t recommend attaching and removing it more than 5 times).
We recommend attaching the Wallet to a case. Flexible cases make removing the Wallet easier. The type of case you use will have a big impact on the life of your Wallet's adhesive. We don't recommend anything that would peel off with the Wallet on removal, like leather.
Use caution when removing if attached directly to your smart phone, we don't recommend using anything to pry the Wallet loose, as you may scratch or damage your phone.
You will need to Reset your Wallet, to put it in pairing mode. Merely use a paperclip and press the reset button (#7 shown in the image below). Once the reset button is pressed, the Arc should flash a red light letting you know it is ready to pair.
