Project Diagram

The whole project is built with three parts: Raspberry Pi, Flask, and Zapwork.

Firstly, I use RC522 as RFID read to read the ID number of the tag and camera module to take a photo if needed.

Then both Information and photo ID can be stored in the database where personal details can be loaded whenever scanning the

tag again.

Finally, I send the Zapcode to the email address through Flask and use Zappar App to scan it to get the virtual contact card.

Create a new customer:

• Pick a photo ID, either copy the image address or take photo with camera module
• Fill the personal information on the website linked by Flask
• Create a new Zapcode on the Zapwork website
• Store all information above and a random identification number in the database
• Get those information and create the personal information page of the customer
• Scan the RFID tag to link customer ID with all information in the database
• Send both information page and Zapcode as an attachment through Gmail
• Use Zappar to scan the Zapcode to get the new virtual contact card

Read existed customer's information:

• Scan the RFID tag to get the customer ID
• Check whether the customer existed. If not, turn to the "create" page
• Get the information with customer ID through the database
• Get the personal information page with the information
• Send the page and Zapcode to the customer gmail address
• Use Zappar to scan the Zapcode to get the customer's virtual contact card

Edit existed customer's information:

• Scan the RFID tag to get the customer ID
• Check whether the customer existed. If not, turn to the "create" page
• Edit the photo id and information except for customer ID number on the "Edit" page
• Edit Zapcode on the Zapwork website
• Edit the database with all information above
• Scan the RFID tag again to link customer ID with all new information in the database
• Create a new personal information page
• Send both information page and Zapcode as an attachment through Gmail
• Use Zappar to scan the Zapcode to get the new virtual contact card

Delete Flow Digram

Delete customer:

• Read customer id through RFID reader
• Check whether the customer already existed
• Clear personal information Page
• Clear all data of customer in the database
• Archive Zapcode on the Zapwork website
• Reset tag with ID "0"
• Send “Delete done" to the customer gmail address

I use RC522 as a RFID reader, Camera module for photo taking, and Raspberry Pi as core system of the project.
