Why do you want images of my receipts?

We can use the information on your receipts to understand the stores that you use and the types of products that you buy. This helps us to advise manufacturers and retailers about how well their products are performing.

How should I capture long or double-sided till receipts?

Please try and photograph the whole receipt in one image. However, if it is very long (e.g. a grocery trip with more than 30 items) or a double-sided receipt you can take multiple photos. Please ensure you fit everything on the receipt is captured in the images.

Alternatively, you can cut very long receipts into sections (up to 3 parts) and take a picture in a single image.

Can I photograph multiple receipts in a single image?

No, please include only a single receipt in each image.

I have submitted the same receipt twice. What should I do?

We suggest that it is best to send receipts as soon as you receive them so you don't forget. However, we can identify duplicate receipts and remove them from our data so you don't need to do anything if you make a mistake.

Please note that you will only receive a single reward for submitting the same receipt multiple times.

Can I check which receipts I've already sent?

It is not currently possible to see details of which receipts you have sent us. We hope to provide an option to view this in the future.

When do I receive my rewards?

The rewards for the receipts you submit will be credited to your reward account on a weekly basis. E.g. for receipts you send us this week we'll add the rewards to your account the following week.

Your reward for registering will be included in the rewards you receive for your first week's participation.

We'll send you an update of your reward account balance when rewards are credited.

How can I check my rewards balance?

Rewards will be credited to your reward account on a weekly basis and we'll notify you with an update of the balance and a link to redeem your credit for gift vouchers.

Alternatively, please contact the helpdesk to check your balance or make a redemption at any time.

My receipt shows credit card details, how can I remove these?

You can cover the card number or blank it out using a pen but please do not cover any details about the items purchased, price or the store or date.

Please also do not cut off the bottom of the receipt as often this includes the date and time of the trip which is very important to us.

How much data does it take to send a receipt?

The amount of data required to send an image depends on your phone's camera resolution. Most smartphone cameras typically have a resolution of 3 megapixels or higher. Images at 3 megapixels will be around 500 kilobytes (0.5 megabytes).

On some smartphones it is possible to adjust the resolution of the camera, if so please set the camera to use at least 3 megapixels.

Can I transmit by wi-fi only?

Yes, if you have a low data allowance on your mobile phone plan you can choose to transmit data over wi-fi only.

In the ShopandScan app home screen press the 'Menu' button then select the 'Settings' option and check the box for 'WiFi only'.

If you choose this option please remember to connect to a wireless network regularly in order to send your data.

Can I send receipts by post?
