According to the Gemalto, the Optelio sticker is a microprocessor-based secure personal device that provides a compatibility solution to enable contactless functionality for handsets that don’t have contactless features built-in.

By attaching the Optelio contactless sticker to their mobile phone, UniCredit customers will be able to use the contactless feature on payments under EUR20, while larger amount transactions will require a PIN code.

Payments can be made in fast food restaurants, cinemas, supermarkets and other retail outlets across the Slovakia, with its established contactless payment market of over 3,000 acceptance points in place.

Gemalto said its Optelio contactless sticker has been designed to work on any handset model. It also provides sticker personalization, packaging and delivery to the end user as part of the service to UniCredit.

Gemalto claims the Optelio contactless sticker has achieved MasterCard certification and complements a full set of Gemalto services already available for mobile payment.

UniCredit Bank Retail Banking Division head Monika Kohutova said the MasterCard Paypass sticker, which the bank named StickAir, is another unique product modeled upon requests and needs of customers of UniCredit Bank.

"It can be issued in relation to any current account open with UniCredit Bank and our customers can affix the StickAir wherever they want, like for example to the rear of their cell phone," Kohutova said.
