On July 11, according to foreign media reports, Nokia will soon launch Perks, a smartphone-based group purchase service. Similar to Groupon, after the user selects a merchandise on Perks, the mobile phone will receive the promotional code and present the discount code at the time of purchase. It will also incorporate mapping software that will mark the location of the business on the map.
The paperless coupon system also supports hotel search and direct booking services. Groupon uses ThePoint platform to manage its business-related services. Perks is currently only a separate discount system and has not added any features. Groupon relies on the number of people involved in the purchase to achieve the transaction. The low number of participants means that the transaction cannot be reached on that day.
From the video of Perks uploaded on the Internet, it is unclear how its system will work, but it looks simple and convenient. Only after the official announcement can you know if it is as effective as it seems.
