TORONTO -- Tim Hortons has joined other Canadian retailers in adding Interac Flash cards to the number of ways customers can make cashless payments at the counter.

The restaurant chain expects more than 2,300 locations across the country to be accepting the wireless touch cards by the end of October.

Rather than adding to a credit card balance, the Interac cards draw down the funds from the customer's bank account.

Unlike older types of credit and debt cards, the new generation of Interac cards use a quick-touch wireless reader rather than a swipe stripe or computer chip.

Due to its size, Tims will be one of Canada's biggest users of Interac Flash but it won't be alone.

Indigo book stores, Cineplex movie theatres and Esso-branded convenience stores are among the retailers that have said they'll join the Interac Flash mob.

In most other announcements so far, however, the retailers don't expect to have their locations up to speed until sometime in 2013.

But Tim Hortons Inc. (THI) said Tuesday it expects to have more than 3,000 restaurants accepting Interac Flash by the end of this year.
