Nej\u010dast\u011bj\u0161\u00ed hrozby, kter\u00fdm \u010delit<\/h3>\n

Co d\u011bl\u00e1 Visa a pro\u010d byste m\u011bli poslouchat?<\/h2>\n

Visa neust\u00e1le aktualizuje protokoly, p\u0159id\u00e1v\u00e1 biometrick\u00e9 ov\u011b\u0159ov\u00e1n\u00ed a roz\u0161i\u0159uje limitovan\u00e9 karti\u010dky, kter\u00e9 jsou odd\u011bleny od hlavn\u00edho \u00fa\u010dtu.

Praktick\u00fd krok, kter\u00fd v\u00e1m zachr\u00e1n\u00ed pen\u00edze<\/h3>\n

Mimochodem, pokud jste u\u017e n\u011bkdy ztratili sp\u00e1nek kv\u016fli podez\u0159el\u00e9 transakci, ud\u011blejte si to jednou prov\u017edy: aktivujte okam\u017eit\u011b notifikace v mobiln\u00ed aplikaci va\u0161\u00ed banky.
