Need some help with Electromagnetic locks, LCD Screen, Smart card Reader and Battery Power! Answered
I am designing a locking device (see attached image) that will house a smart card reader, a small LCD screen (roughly 80mm x 20mm) and a small electromagnetic lock that will need to withstand reasonable force.
The overall device will be no bigger than 140mm x 80mm x 40mm
I would like to know whether a rechargeable battery would be able to power the LCD screen, electromagnetic lock and smart card reader. If so how big and what size would that battery need to be?
How would an LCD screen be programmed to take information off of a magnetic strip and display it on the screen?
I would also like to know some names for the components that would be required to operate all of these components.
Thank you to anyone who comments.
