Consumers can now use Visa debit cards for smaller purchases without entering a personal identification number, the same way they can skip signing receipts.

Visa said Tuesday it is no longer requiring merchants to treat its debit cards differently when customers use them as PIN-debit cards, as opposed to signature cards.

The move prompted the Justice Department to drop an antitrust investigation of the practice.

Visa has allowed banks to permit merchants to waive the signature requirement when customers use Visa debit cards, usually on small purchases below $25, the department said. But Visa has prohibited banks from allowing merchants to waive the entry of a PIN if a customer chooses that route.

Visa said it is ending the prohibition on waiving PINs effective Tuesday.
