DASECURE SOLUTIONS LLC · SAN FRANCISCO
Proof of who, what and where
Three products that answer the three questions every real-world transaction turns on — who is this person, what are they entitled to, and did the moment actually reach them.
Each one stands alone. Used together they replace a stack of passwords, plastic cards and unread email.
The platform
Three products, shipping today on the web, iOS and Android.
ZapQR
Identity
The passwordless sign-in button for your site
A hosted OIDC identity provider. Drop “Sign in with ZapQR” into any site and your users sign in with a passkey — or by scanning a QR code with their phone, which is the only way in on screens that can't hold credentials: kiosks, TVs, cars, staff terminals, signage.
Proved on an $80 UNIHIKER — a 240×320 screen with no keyboard, signing in over RFC 8628 with nothing but stdlib Python.

PassQR
Credentials
Apple & Google Wallet passes for real businesses
Issue loyalty, membership and access credentials that live in the wallet your customers already carry. Stamp cards that update on the lock screen the moment a barista scans, a browser-based scanner for the counter, and an API for everything behind it.
iotPush
Delivery
One curl away from your pocket
Push notifications for servers, scripts, agents and IoT devices. One HTTP call sends to a topic; the app on your phone can answer back with action buttons and typed replies, so an alert becomes a decision instead of a dead end.
Better together
These aren't three unrelated apps under one roof. Identity, credential and delivery are the three halves of the same problem — so each product is already a customer of the other two.
Layer 1 · Identity
ZapQR
Who are you?
Layer 2 · Credentials
PassQR
What do you hold?
Layer 3 · Delivery
iotPush
Did it reach you?
ZapQR ──▶ PassQR + iotPush
Both admin consoles sign in through ZapQR. One identity, no separate passwords to lose.
ZapQR ──▶ iotPush
Every sign-in raises a push on your phone — and a session you can end from it.
PassQR ──▶ iotPush
Scans, stamps and usage reports arrive as notifications you can act on, not dashboards you have to remember to open.
iotPush ──▶ PassQR
When a message matters, it lands twice: as a push, and as a live update on the wallet pass already on the lock screen.
The compounding effect is the point: adopt one product and the next one costs you an afternoon instead of a quarter, because the identity, the credential and the notification channel are already wired.
In the lab
What the three layers make possible once they compose.
PassQR Tag
Presence
Reach the owner. Prove you were there.
A QR tag on a car, a bag, a badge or a door. A stranger scans it and can reach the owner without either side learning who the other is. What makes it more than a sticker is presence: the tag proves the sender is actually standing there — by Bluetooth beacon, by location, by a live photo with the code in frame — and how urgent the message is decides how much gets disclosed and how fast it escalates.
Uses all three layers at once
Owners sign in with ZapQR. Alerts arrive over iotPush and land on the lock screen as a live PassQR wallet pass. Passers-by stay anonymous throughout — no account, no app, no phone number.

About us
DaSecure Solutions LLC is a software company in San Francisco, California. We build the plumbing for trust between strangers — identity, credentials, presence and the alerts that tie them together — and we ship it ourselves, end to end.
One hard problem
Everything we ship answers who, what or where. We stopped building anything that doesn't.
Shipped, not slideware
Live on the App Store, Google Play, the Chrome Web Store and wordpress.org — not a roadmap.
Composable by default
Each product is a customer of the others. That's how we find the sharp edges before you do.
