The first version of the SmartWallet is the standard wallet which has an integrated BLE chip, and function button on the clip. This version does not have the 1000 mAh battery and is priced lower than the other wallet. The BLE chip in the standard wallet runs off a CR2032 coin battery (like you would find in most watches) which lasts between 1-2 years. When the battery gets low you will receive a notification on the StreetSmart app and you will be able to replace it easily.
Our premium SmartWallet has the 1000 mAh portable battery pack and BLE chip in the clip and a USB and either Micro USB or iPhone Lightning connector in the zipper compartment at the bottom for quick access and storage.
