Abstract: An electronic prescription voucher system provides the security of an electronic prescription while giving a patient control over the selection of a pharmacy and when to fill the prescription after the patient has left a healthcare provider's office. A cloud-based voucher service provides the patient with a printable paper-based prescription voucher or an electronic prescription voucher before he leaves the provider's office. The patient will be able to fill the prescription at a time of his choosing at an EHR or EMR participating pharmacy by using his smartphone to scan a QR barcode on the paper prescription voucher or enter a prescription ID from the prescription voucher on his smartphone. The prescription is then sent to the pharmacy chosen by the patient. The patient will be notified through the system when the prescription is ready to be picked up.
