Oberthur Technologies SA is planning to move its Los Angeles card manufacturing operations to its recently expanded Exton, Pa., plant.

The Pennsylvania facility can produce up to 20 million cards a month, or 20% more than it could before its $15 million upgrade, Oberthur said last week. The Los Angeles site will stop manufacturing cards by the end of March but will continue to be used for card personalization, the Paris company said. The facility primarily produces conventional payment cards; the Exton one also makes smart and contactless cards.

"This is a critical move to maintain cost competitiveness," Martin Ferenczi, the chief executive of Oberthur's business in the Americas, said in a press release.

Oberthur said it has given the affected employees in Los Angeles the option of moving to Exton.
