If you have a hard time keeping track of your wallet, a European company might have the answer for you.

Walletmor is selling an implantable microchip that keeps track of its user’s financial information. The chip, which is about the size of a grain of rice, can be implanted in the user’s hand, which can then be swiped over a card reader to make a payment, according to the company.

The good news is the tiny implant is selling for just $300. The bad news is it’s only available for residents of the U.K., Switzerland and other European countries, Walletmor officials say.
