4. The medical infusion pump system of claim 1, wherein the respective information stored on at least one NFC tag of the plurality of NFC tags comprises a unique identifier, and wherein, in response to the NFC circuit receiving the unique identifier, the control circuitry initiates actions of the portable infusion pump that correspond to the unique identifier.

5. The medical infusion pump system of claim 4, wherein the actions of the portable infusion pump that correspond to the unique identifier comprise calculating a bolus dispensation of the medicine.

6. The medical infusion pump system of claim 1, further comprising an accelerometer electrically connected to the control circuitry, wherein the accelerometer is configured to detect acceleration movement of the portable housing and to communicate the detected movement to the control circuitry, and wherein the control circuitry is configured to compare a characteristic value of the detected movement to a threshold movement value.

7. The medical infusion pump system of claim 6, wherein the control circuitry is configured to activate the NFC circuit, based on the comparison of the characteristic value to the threshold movement value, to wirelessly receive information from an NFC tag of the plurality of NFC tags.

8. The medical infusion pump system of claim 1, wherein the control circuitry is housed in a controller housing that is removably attachable to the portable housing.

9. The medical infusion pump system of claim 1, further comprising a remote control device that is separate from the portable housing, wherein the remote control device is configured to wirelessly communicate with a wireless communication device connected to the control circuitry, and wherein the remote control device includes a second NFC circuit that is configured to wirelessly receive the respective information stored on each NFC tag of the plurality of NFC tags.

10. The medical infusion pump system of claim 1, wherein at least one NFC tag of the plurality of NFC tags includes information that is indicative of one or more settings of the portable infusion pump.

11. The medical infusion pump system of claim 1, wherein at least one NFC tag of the plurality of NFC tags includes information that is indicative of physical exertion.

12. The medical infusion pump system of claim 1, wherein at least one NFC tag of the plurality of NFC tags includes information that automates an entry of a blood glucose reading.
