Your biggest stores see millions of shoppers. Start knowing who they are.
Big stores mean long visits, big baskets and hundreds of colleagues and devices on one floorplate. Purple turns store WiFi into consented shopper data and in-store survey answers, and runs secure networks for colleagues, scanners and tills, on the access points you already own.
- Branded sign-in with CCPA/CPRA consent
- Surveys answered on the shop floor
- Colleague sign-in with Entra ID, Okta or Google
- A private key for every scanner and till

Your stores hold more shoppers than your website. They remember far fewer.
A large-format store can serve thousands of shoppers a day, most of them staying long enough to compare, plan and fill a trolley. Online, every one of those visits would be named and measured. In store, the WiFi is usually an open network that nobody owns, shared with the colleagues and devices that run the building.
A typical large store today
- An open WiFi network that connects shoppers and learns nothing about them
- Head office sees sales by store but not who came in or what they came for
- One shared colleague password, still working for people who left last season
- Scanners, tills and printers on a single key that is hard to change
With Purple
- A branded sign-in that adds consented shoppers to your CRM on every visit
- Surveys at sign-in that ask shoppers what they are planning, store by store
- Colleagues sign in with their work account, and leavers lose access automatically
- Every device gets its own key and VLAN, revocable one at a time
Shoppers, insight, colleagues and devices, each on the right network
Four jobs that usually mean four suppliers, run from one dashboard for every store in the estate by your marketing and IT teams.
A sign-in that builds your database
Branded sign-in with marketing consent, sent to your CRM and loyalty scheme through 400+ connectors.

xPSK gives handheld scanners, tills, label printers and cameras their own key and VLAN.
The first impression on the screen they are already holding
Shoppers in a big store stay long enough to look things up, compare prices and message home, so most will connect if you ask well. Purple puts that moment in your brand, asks for consent in plain words and sends every opted-in shopper to your CRM. Grupo Sanborns added 1.4 million new customers to its database this way across three department store brands.
- Branded captive portal with CCPA/CPRA consent and a full audit trail behind every record
- Email, form and social sign-in, with one tap for returning shoppers
- Opted-in shoppers sent to Salesforce, HubSpot, Braze, Mailchimp and 400+ other connectors
- Different sign-in pages by store, brand, language or campaign
At Grupo Sanborns, 71% of shoppers who signed in to the WiFi became credit card prospects.

Shopper sign-inAsk shoppers what they came for while they are still in the store
A sale tells you what someone bought. It does not tell you the kitchen they are planning, the project they gave up on or why they came in. Purple asks one or two questions at sign-in and builds each shopper profile a little more on every visit. Home Depot Mexico used this progressive profiling to identify 127,700 opted-in shoppers across 27 stores.
- One-question surveys at sign-in, with 120,800 responses at a 96% response rate at Home Depot Mexico
- New and returning shoppers and dwell time for every store, compared across the estate
- Zones inside one store, as Level Shoes did with 40 to 50 zones to compare brand areas
- Grupo Big, formerly Walmart Brazil, spotted a 3% rise in male shoppers and changed its in-store displays
In-store surveysWiFi for hundreds of colleagues, without a shared password
A large store runs on shop floor, warehouse, click and collect and seasonal teams, all needing WiFi on their own phones and store devices. Purple connects them with the work account they already use. It syncs with Microsoft Entra ID, Okta, Google Workspace and JumpCloud over SCIM, and group membership decides which network and policy each person gets.
- Leavers lose access when their account is disabled, with no password to change
- Store, warehouse and head office teams on separate VLANs with their own rules
- Personal phones onboarded in about 60 seconds with the Purple app
- Every session logged with person, device, time and location
Identity-based staff WiFi means 80% fewer IT tickets, backed by a 99.9% RADIUS uptime SLA.

Staff WiFiA private key for every scanner, till and printer
Handheld scanners, card terminals, self-checkouts, label printers, cameras and digital screens cannot sign in with a username. xPSK gives each one its own key and its own VLAN, so a leaked key affects one device, not the whole store, and the tills stay off the shopper network.
- Revoke a single key without re-keying every scanner in the store
- MAC binding ties each key to the first device that uses it
- Works under your vendor's name: iPSK on Cisco, DPSK on Ruckus, MPSK on HPE Aruba and Juniper Mist, PPSK on Extreme and UniFi
- No per-device license and no cap on devices per key
xPSKWhat an open store network gives you, and what Purple gives you
The same access points, doing four jobs instead of one.

Measured in shoppers and answers, not connections
Department store groups, DIY chains and supermarkets use Purple to build their customer database and learn what shoppers want. These are the results they have measured.

Big box retail WiFi questions, answered
What retail marketing, CRM and IT teams ask us most
Do we need to replace our access points?
No. Purple runs on the access points you already own, including Cisco Meraki, HPE Aruba, Ruckus, Juniper Mist, Ubiquiti UniFi, Cambium, Extreme and Fortinet. Coverage across the floorplate comes from your access points. Purple adds the sign-in, data, colleague and device networks on top.
How do shopper details reach our CRM?
Every shopper who opts in is sent to your CRM, email platform or loyalty scheme through 400+ data connectors, including Salesforce, HubSpot, Braze and Mailchimp, with the consent record attached.
Can we ask shoppers questions in store?
Yes. Add one or two survey questions to the sign-in, or build a shopper profile a question at a time on each visit. Home Depot Mexico collected 120,800 responses at a 96% response rate across 27 stores.
Is shopper data collected in line with CCPA/CPRA?
Yes. Consent is asked in plain words at sign-in and recorded with a full audit trail. Purple is ISO 27001 certified, CCPA/CPRA compliant, and has had zero data breaches since 2012.
How do scanners, tills and printers connect?
With xPSK. Each device gets its own key and VLAN, bound to the first device that uses it, and kept apart from the shopper network. You can revoke one key without touching any other device.
What happens when a colleague leaves?
When their account is disabled in Microsoft Entra ID, Okta or Google Workspace, SCIM revokes their WiFi access automatically. They cannot reconnect, and there is no shared password to change.
Can we manage every store from one place?
Yes. Every store, sign-in page, survey and network is run from one dashboard, with results for each store and across the estate.
