Making it compatible with braille - adding perforated dots during the printing process would make this more accessible.
Color scheme - Adding different types of color schemes instead of relying on monochromatic labels could convey more information to the pharmacy technician and act as a further layer of safety.
Direct printer compatibility - at present, the text is generated over an image; ideally, this could save a complete image in a printer-compatible format.
Autofill patient data - linking the label maker to a database of patient data would reduce redundancy and reduce human-inputted error.
Add images of pills to the label- adding images to the label could help ensure that the pharmacy technician took the right pill for the right label before it is final, and give the patients more information on their medication.
Make it compatible with an app - this could streamline a lot of the processes by making use of Bluetooth and electrical components. This app would include a timer, possibly a way to open the bottle through the app only, and could connect to the pharmacy's own database to tell when to refill.
Make it more universal - this would make it more efficient to make but as it stands the tube at the top only is supposed to fit for one type of medication but the plan is to make it adjustable and universal to all pill types.
