Digital Scratch Card Maker: Build a Virtual Scratch Card in 15 Minutes

A digital scratch card is the cheapest interactive mechanic you can put in front of a UK customer. There is nothing to explain: the customer rubs a thumb across the screen, the foil clears, and a prize appears. No rules to read, no form to fill in before the payoff.

That lack of friction is why the format survives every trend cycle. Paper scratch cards have done this job for decades in newsagents and petrol stations. The digital version does the same thing on a phone, but it captures the data, proves the redemption, and can be changed between campaigns without reprinting anything.

This guide covers what a digital scratch card is, how to build one in about 15 minutes, which prize structures protect your margin, and what UK law requires before you let anyone scratch.

What a digital scratch card is

A digital scratch card is a browser-based game in which a customer reveals a hidden prize by swiping a finger over a covered area of a phone screen. It runs from a QR code or a link, needs no app install, and can be branded, localised, and tied to a specific promotion. The operator decides the prize mix and the rules.

Two things separate it from a paper card. First, the entry is logged, so you know how many people played, when, and from where. Second, the mechanic is a consent gate: the customer identifies themselves to receive the prize, which is the whole point for a business that wants to contact them again.

Why UK businesses are moving from paper to digital

The UK is a mobile-first market. 89.4% of UK adults have scanned a QR code, one of the highest adoption rates in Europe, and UK consumers now spend around 4.1 hours a day on a smartphone (Ofcom). The physical card in a customer's hand is increasingly a phone in a customer's hand.

At the same time, high-street footfall has been falling by roughly 3.5% year on year (BRC). Anything that gives a passer-by a reason to stop, interact, and come back has to earn its place. A scratch card does that with a two-second interaction rather than a thirty-second explanation.

Four practical differences matter:

• No print run. Changing the prize, the branding, or the language means editing a campaign, not ordering 5,000 cards.
• Consent built in. The customer gives contact details to claim the prize, with a lawful consent record attached, instead of leaving a paper stub nobody processes.
• Measurable. You see scans, plays, completions, opt-ins, and redemptions per placement and per day.
• Hard to abuse. One entry per device, time-stamped, with the prize tied to a unique code rather than a torn cardboard stub.

How to build one in 15 minutes

The build is short because a scratch card is a simple object: a cover, a prize underneath, and a data-capture step. Work through the seven steps below in order and keep the first campaign deliberately plain.

1. Pick the job the card has to do (2 minutes)

Choose one objective, not four. A card that offers a discount, asks for a review, collects an email, and promotes a loyalty programme does none of those things well. The three objectives that work: bring people into the shop, capture contact details for a list, or move a specific product line.

2. Choose the mechanic and the plan (1 minute)

On QronoPlay the scratch card (alongside the instant win) is one of the two formats included in the Starter plan, so a single-campaign test costs EUR 19.90/month (approximately GBP 17) excluding VAT. If you need a spin wheel, a quiz, or a prize draw in the same campaign calendar, those sit on Pro at EUR 29.90/month.

3. Set the prizes and the odds (3 minutes)

Decide the prize ladder before you touch the design. Write down what a winner gets, what a near-miss sees, and what the maximum exposure is if every single participant wins the top prize. If that number makes you uncomfortable, the ladder is wrong. The next section covers five structures that hold margin.

4. Brand the card (3 minutes)

Upload the logo, set the foil colour to the brand palette, and write one line of copy. Keep the prize name short enough to read at arm's length on a phone: "Free coffee", "20% off", "Glass of house wine". A prize that needs a sentence of explanation is a prize nobody claims.

5. Add the data-capture step and the consent text (2 minutes)

Ask for the minimum you will actually use: email address, plus first name and postcode if you plan to segment by location. The consent line must be specific and unticked by default. "Tick to receive offers from [business]" beats "I agree to the terms and privacy policy" on every measure that matters, including UK GDPR validity.

6. Generate the QR code and test on a real phone (2 minutes)

Build the campaign, then scan the QR code with a phone that is not yours and is not logged into the dashboard. Test the slow path: a customer with a weak signal, an older handset, and no account. If the prize does not appear within a few seconds of the first swipe, simplify the page.

7. Print, place, and watch the first 48 hours (2 minutes)

Put the code where the decision happens, not where the poster fits. Then leave it alone for two days and read the numbers before you change anything. Most first campaigns are changed too early, which makes the second week's data unreadable.

Five prize structures that protect your margin

The prize ladder does more commercial work than the design. These five structures work for UK retail, hospitality, and services, and each one keeps the cost of a redemption predictable.

Structure	What the winner sees	Why it works
Tiered discount	10%, 15%, or 20% off, revealed at random	A 10% result still feels like a win and the average discount stays below the headline rate.
Free add-on	Free side, dessert, drink, or sample with a purchase	Cost is predictable, and the redemption is an upsell rather than a markdown.
Access, not money	Early entry to a sale, priority booking, a reserved slot	Zero marginal cost, and it recruits customers who plan ahead.
Experience prize	Upgrade, tasting, workshop, behind-the-scenes visit	High perceived value against low hard cost, and it creates something to photograph.
Consolation that still converts	"Not this time, but here is 10% for today"	Keeps the loss rate from feeling like a dead end, which is where most abandonments happen.

One warning: do not stack a discount on a product that already carries a promotion. The card stops reading as a reward and starts reading as the normal price, and the customer learns to wait for the next card.

Where to place the QR code

Placement decides the result more than the creative. The rule is proximity to the moment of decision: a code on the till receipt is scanned days later, a code on the table is scanned while the customer is still deciding what to order.

Placement	Best for	Watch out for
Table tent or menu card	Cafes, pubs, restaurants	Codes that sit under a drinks menu get covered.
Till point and receipts	Retail, convenience, salons	Volume is high, intent is low; expect a lower completion rate.
Product packaging or shelf edge	Grocery, beauty, drinks	Needs a reason to scan now rather than at home.
Window vinyl	High-street shops	Reflections kill scanning after dark.
Event stand or sampling table	Markets, festivals, trade shows	Staff must demo the first swipe, or most people walk past.
Email and social footer	Existing list	Not a QR play, but the same card works as a link.

UK legal checklist before you launch

Four pieces of UK regulation apply to a scratch card promotion. None of them is complicated, and all four are cheap to get right before launch and expensive to fix afterwards.

Gambling Act 2005

A promotion where a prize depends on chance and entry requires a payment is a lottery, and running one without a licence is an offence. The standard way to stay on the right side of the Act is a genuine free entry route: no purchase necessary, and an entry route that does not require a purchase, stated in the significant conditions. Keep that route available and documented.

CAP Code and the Advertising Standards Authority

Sales promotions are covered by the UK Code of Non-broadcast Advertising (CAP Code), enforced by the ASA. The significant conditions of the promotion, including the closing date, the prize, and the free entry route, must be presented clearly and not buried. "Subject to availability" and "prizes may vary" do not fix a promotion that was never clearly explained.

UK GDPR and the Data Protection Act 2018

The scratch card exists to collect data, so data protection is the operative risk. You need a lawful basis, a privacy notice linked at the point of entry, a consent record, and a process for erasure requests. QronoPlay is hosted in France, covered by the EU adequacy decision that lets personal data flow from the UK to the EU without additional safeguards, and includes CSV export of collected contacts so the data sits in your systems rather than only in a third-party dashboard.

Consumer Rights Act 2015

Terms must be transparent and prominent before the customer enters. If the prize is a voucher, state the expiry date and the exclusions on the prize screen, not only in a terms page. If the promotion involves alcohol, apply the usual age verification and do not make the prize the reason to drink more.

What it costs

QronoPlay is self-service, priced in euros, with no setup fee and a 14-day free trial that does not require a card. Prices exclude VAT.

Plan	Monthly	Annual	Games and limits
Starter	EUR 19.90 (~GBP 17)	EUR 199/year	2 games including the scratch card, 1 active campaign, 1,000 participations
Pro	EUR 29.90 (~GBP 25.60)	EUR 299/year	13 games, unlimited campaigns, 20,000 participations
Business	EUR 99.90 (~GBP 85)	EUR 999/year	19 games, unlimited campaigns, 100,000 participations

For a single shop testing one campaign, Starter is enough. The step up to Pro is worth it when you want a scratch card and a spin wheel running at the same time, or when a month's participation count will pass 1,000.

Proof that the mechanic captures at scale

Two QronoPlay campaigns show what a well-placed QR code does to a customer list. A venue in Normandy collected 990 contacts in 25 days with an anniversary game. The French news site actu.fr collected 14,997 entries in 25 days with a digital Advent calendar. Neither was a scratch card, but both used the same mechanics a scratch card relies on: a QR code, a mobile page, a reason to enter, and a prize worth claiming.

Those numbers are also a fair warning. The campaigns that produce them have a clear prize and a single call to action. A card offering three prizes and two messages produces a fraction of the same result.

Four numbers to watch after launch

• Scan-to-play rate. Scans that turn into a completed game. A large gap here means the landing page is slow or the offer is unclear.
• Opt-in rate. Players who accept contact. This is the number that decides whether the campaign built an asset or just gave away discounts.
• Redemption rate. Prizes actually claimed in store. A high win rate with low redemption means the prize was not worth the trip.
• Repeat rate. Contacts who engage again within 90 days. This is the only number that tells you whether the card bought a customer or a one-off discount hunter.

Start with one card, one prize, one placement

The failure mode is not technical. It is launching four placements, three prize tiers, and two objectives at once, then being unable to tell which part worked. Put one card in one place, run it for a fortnight, and read the four numbers above. The second campaign is where the margin comes from.

You can build the first one today: compare the QronoPlay plans, start the 14-day trial, and publish a scratch card before the end of the afternoon.
