QR Codes for Blood Donation: Donor Registration, Appointment Booking, and Unit Tracking

1. Donor Recruitment

A QR on a campaign poster links to the donor eligibility check and appointment booking page. Fast mobile booking increases donation rates from campaign-prompted visitors.

2. Appointment Check-In

Donors scan a QR at the centre to check in and confirm their appointment. This reduces queuing and feeds the donor management system automatically.

3. Unit Tracking

A QR label on each blood unit links to the chain-of-custody record: donor anonymised ID, collection date, testing results, and storage log. Hospital staff scan to verify the unit before use.

4. Privacy

Donor identity must be protected throughout the chain. Use opaque tokens on blood unit labels; never expose donor names or health data in plain text on a printed label.
