Retailers need to understand what value for their consumers, their employees and their organization can be unlocked through using location services, and then incrementally introduce the change over the coming years.
And finally, it's important to note that there's not a one size fits all approach. As you embark on this journey, these are some technical questions to consider:
Do you partner or build in house? If you partner, who do you partner with?
Should you be pushing these new services through your own app, a 3rd party app or a native mobile wallet?
What logic controls the events and notifications that consumers receive so as to be ‘cool’ not ‘creepy’?
And of course, should you use beacons, geo-fencing, Wi-Fi, NFC or a combination of these? A summary of these technologies can be accessed here.
