It can be transferred physically for payments. The representatives of Tangem call this solution a «copy-protected cold wallet».

Besides, it is noted, that “many years of chip development for credit, identity and SIM-cards led to creation of safe product”. Now the expenses to hack one banknote areeconomically unprofitable.
