How secure is buying a wallet from marketplaces?

Tangem cards cannot be physically modified, as there is a monolithic chip inside the card. The software in Tangem cards cannot be modified.

The official app can accurately verify the following:

— that the card was produced by Tangem;

— that the card is flashed with Tangem software.

It would even be totally safe to buy in an underpass, thanks to its end-to-end certification. Most importantly, make sure that:

1. You have installed the official Tangem app.

2. The cards prompt you to create a wallet. If they do not, reset the cards to factory settings.
