Visa Rolls Out Its Smallest Contactless Payment Fob

Visa on Wednesday introduced what it said was its smallest payment device ever. The Visa Micro Tag is a contactless fob designed to hang off of a keychain.

Visa has waived the requirement to have an account number embossed or printed on the device, in an attempt to boost security. The new payment device will be issued as companion devices to existing credit, debit and prepaid cards, Visa said.
