Tile Slim ($30 and up)
At roughly the size of two credit cards, this Bluetooth device will make anything large enough to hold two credit cards much easier to find. Using the iPhone or android app, the tile can be made to beep loudly any time it’s within Bluetooth range. Most times at home, a misplaced wallet isn’t far away, but hiding somewhere out-of-sight. Conversely, if you have your wallet but can’t find your phone, a pushbutton on the tile will cause the linked phone to make noise.
