How it works
Nothing changes at the till. The customer pays the way they always do, then taps their phone on a small SkipSlip tag on the counter. That's it: no app, no account, no QR code to scan, no email address to type in.
The sale goes through the shop's normal checkout system. SkipSlip connects to that system, so the receipt comes from the real, completed sale, not a copy typed in by hand.
Hold the phone near the tag. iPhones from the XS onwards read NFC tags without any app[1], and so do Android phones with NFC turned on[2]. The phone simply opens a link.
Every tap carries a fresh cryptographic signature from the tag's chip[3]. Our server checks it, then matches the tap to the sale that has just completed at that counter.
The receipt opens on a permanent page of its own. Customers can come back to it, save it as a PDF or share it, and it carries a QR code the shop can check for returns.
The Qatar Green Building Council estimated that the country gets through 5.4 million sheets of paper a day[4]. Every receipt that's glanced at once and thrown away is part of that pile.

The problem with paper receipts
Most receipts are printed on thermal paper: paper coated with chemicals that darken when the printer heats them. That coating is what makes them quick to print, and it's also the problem.
used to make receipts in the United States alone, along with 9 billion gallons of water, 302 million pounds of solid waste and over 4 billion pounds of greenhouse gases[5].
are coated with bisphenol A (BPA) or bisphenol S (BPS), chemicals that rub off on the fingers of anyone handling them[6][8].
thermal paper containing more than 0.02% BPA by weight can't be sold in the European Union[7].
a US state environmental agency found thermal paper is likely a major source of BPA in recycled paper, carrying the chemical into new paper products[8].
Detailed receipt statistics are published for the United States and the EU; comparable figures for Qatar aren't available yet. The chemistry of thermal paper is the same wherever it's used.

Who benefits
Security and trust
A digital receipt is only useful if shops and customers can trust it. SkipSlip is designed around that from the chip up.
SkipSlip tags use the NXP NTAG 424 DNA chip, which uses AES-128 encryption and generates a new authentication message every time it's read[3]. Each tag is programmed with its own keys.
Each tap produces a unique, signed link containing a counter that only goes up. A copied or screenshotted tap link is rejected, so nobody can claim a receipt by replaying someone else's tap.
Receipts are created from completed sales reported by the shop's checkout system, and that report is itself signature-checked. A receipt can't be made up by typing in a total.
The QR code on every receipt opens SkipSlip's own record of the sale, checked live. If a customer's copy has been edited, it won't match; if it was invented, the check says so.
SkipSlip never receives full card details. Like a paper receipt, it shows at most the card type and last four digits.
No app, no account, no sign-up: customers don't hand over a name, phone number or email address to get their receipt. Receipt pages are hidden from search engines.
For merchants
One small NFC tag on the counter, connected to your checkout system. No new hardware for your staff to learn and no app for them to install: they keep ringing up sales exactly as they do today.
We're starting with a small number of pilot stores in Doha.

No. Tapping the tag opens the receipt in the phone's normal web browser. iPhones (XS and later) and NFC-enabled Android phones read the tag without any extra software[1][2].
The shop can still print a paper receipt. SkipSlip replaces paper for everyone who's happy without it; it doesn't take the choice away.
Each receipt has its own permanent page. Customers can bookmark it, add it to their home screen, share the link or save it as a PDF.
Not successfully. The shop scans the receipt's QR code, which shows SkipSlip's own record of the sale, checked live. An edited copy won't match that record, and an invented one won't be found at all.
Every tap produces a new signed link with a counter that only ever increases, and each link can be used once. A copied link is rejected.
SkipSlip connects to a shop's checkout system so receipts come from real sales. Our first integration is built and tested, and we're adding checkout systems used in Qatar as we start our pilots. Tell us which one you use.
The details that appear on the receipt: the amount, the time, the receipt number and, if the checkout system provides it, the card type and last four digits. Customers don't give us their name, phone number or email address.
We're launching in Doha with pilot stores. If you'd like SkipSlip at your store, get in touch below.
