Write it. Seal it. Send it.
Your prescription goes straight to your patient's phone with a digital signature. Any pharmacy can check it in a second, and nobody can copy it, change it or use it twice.
Your sealed prescription will appear here.
Sent to the patient's phone. They show it at any pharmacy.
How the seal works: your browser signs the prescription with a private key that never leaves this device (ECDSA P-256). Changing even one letter makes the signature fail.
