im using PHP programming Language and im using RFID but i have a problem , how can i function the rfid if i tap the id card then automatic send SMS to parents
Meron ka bang RFID scanner? Kailangan mo ng Interface between your PHP application and RFID scanner. Ang RFID scanner ay pareng barcode scanner din yan may lalabas na numbers na iinput tulad ng textbox.
Gaya ng sabi ko ang RFID ay parang barcode scanner lang yan. Kailangan mo lang ng Textbox na imomonitor mo sa CHANGE event. Kailangan mo lang na laging may FOCUS sa Textbox nagagamitin mo. So every TEXT CHANGE event mag-titrigger ang function mo.
When you use a barcode scanner, it won't automatically send SMS. There is no free lunch here. You need to program that either by writing one from scratch (bad idea) or leveraging existing APIs and services, example Twilio.
Let's ignore for now the barcode scanner. Can you write a program that can send SMS by leveraging existing APIs or services? If you can't the barcode scanner is not your problem.
