LONDON—Visa Europe is holding weekly meetings to discuss scenarios in the event the euro zone collapses, joining other companies that are preparing for a potential breakup of the currency bloc.

Chief Commercial Officer Steve Perry said Tuesday that management at the U.K.-based credit-card company meets weekly to explore various possible outcomes, including a total collapse of the euro zone.

"From our perspective, we can implement new currencies at the drop of a hat," Mr. Perry said on the sidelines of the BRC Retail Symposium conference. "If a collapse were to happen, or an individual country were to leave the euro, we could handle that very quickly in terms of allowing people to use their cards in a payment capability."

Visa Europe is the European licensee of Visa Inc. and has been a wholly separate entity to the U.S. company since 2007. It generates all of its revenue in Europe, so it is more vulnerable to a breakup of the euro zone than its rivals.

Many companies have drawn up plans to respond to a deepening of Europe's financial crisis, Greece's possible default on its debts and an exit from the euro zone, examining such contingencies as paralysis in cross-border payments, civil unrest and the breakup of the single currency.
