Octopus, photos in 7-Eleven services

All 7-Eleven stores across Hong Kong will offer Octopus card recharging and photo-processing services by the end of the month.

The convenience store chain has also upgraded 11 of its stores, offering new products and services, and spent $2 million on a promotional campaign.

On July 11, the chain's promotion day, customers will be offered perks, including a lucky draw and shopping vouchers.

Some 711 young customers will be given places at a summer camp and free tickets will be given out to a pop concert in September.

Chief executive for Hong Kong and South China David Tso said the company undertook a campaign to meet growing competition in the retail sector.

'Hong Kong's retail environment is very tough [at the moment],' Mr Tso said.
