A hardware health line. No phone to charge, no app to open — the card in your wallet reads your body-worn devices, warns you before a dangerous moment, and runs for a week between charges.
If the readings are alarming, the card itself sends them to the supervising doctor or to emergency services. No cellular coverage — it goes via satellite.
There are a great many people with conditions, and not all of them carry a phone or a watch. The card simply sits in the wallet.
A motion sensor built into the card detects a fall. The next step we are working on is noticing unsteadiness in advance — whether the person is swaying or not. That is an important sign in many neurological conditions — Parkinson's, post-stroke states, age-related changes where people fall. The card raises an emergency call and sends a message — to the doctor, to the family, to a medical platform.
And the key point about older people: they forget to charge the phone, they leave things everywhere. But the wallet is always carried — and in it lies not one card but several, each with its own function.
Glucose meters often get left at home. A card that is always in the wallet is harder to forget. It does not diagnose and does not prescribe: it tells the person right on the screen that a reading looks abnormal, advises them to re-check and contact their doctor — and if a reading is dangerous, the card itself sends it to the supervising doctor or to emergency services.
The cost of missing it is not inconvenience. Hypoglycaemia can end in loss of consciousness, a head injury and intensive care. Warning the person before that moment is the whole point of the card.
Today every device worn on the body needs a phone. A glucose sensor, a pacemaker, a blood pressure monitor — each one talks to its own app, and the person has to carry a charged phone or the monitoring simply stops.
It receives readings from the devices over Bluetooth, shows them on the screen and sounds a loud alarm on a dangerous value — the way an alarm clock on the bedside table works at night. It then sends the data on to the patient's own record over the cellular network, and where there is no cellular coverage, via satellite. If the readings are alarming, the card itself — with no action from the person — sends them to the supervising doctor or to emergency services. The doctor can send a message back to the card.
Continuous glucose monitoring sensors.
Wireless-capable models — planned together with manufacturers: battery status, rhythm disturbances.
Blood pressure monitors, pulse oximeters, thermometers, scales, body composition analysers — over open international Bluetooth standards.
Smart inhalers and spirometers for asthma and COPD.
Pumps and smart pens — every injection is recorded.
Sensor-equipped pill boxes and call-for-help buttons. Built into the card itself: a fall sensor and a microphone.
Devices using open Bluetooth standards work with the card directly. Closed systems from major manufacturers are connected through partnerships with them.
Blood group, allergies, current medication, the doctor's contact and an emergency-access QR code to the patient record stay visible on the screen at all times. The card runs for a week between charges.
Who it is for: people with diabetes, heart conditions or asthma; older people living on their own; care homes and clinics monitoring their patients.
Small inference chips already sit in almost every flagship phone. Nothing stops us from putting one in a card.
The chip sits in the health card and looks at everything at once — device readings, the motion sensor and the built-in microphone: how the person walks, how they breathe, how their voice sounds, what the glucose is, what the temperature is. Taken together, it notices when the person's condition drifts from their normal — often before they notice it themselves.
Then the card contacts the physician or the medical centre. It takes the rough measurements upon itself and gives not a diagnosis but a danger signal: re-check, sit down, call for help.
The emergency screen's QR code and the readings this card collects are meant to land in one place: a patient's own medical record, not a pile of separate apps. That record — visits, documents, prescriptions, a doctor a patient can actually reach — is what we are building in OneMed. The card is the sensor at the edge; OneMed is where the record lives.
This line is in development — first samples. The card collects, displays, warns and transmits. It does not diagnose.
