Do you think this can be done with a magnetic strip rather than a computer chip. If so would it be less complicated, easier? Thank you for your help!!!!

I am not very familiar with electronics and am wondering if someone can assist me or at least point me in the right direction. I am wondering if a micro computer chip, say smaller than a dime can easily be affixed to an object and transmit an alert (beeping noise) to a receiver or piezo sensor/speaker when the two are separated by say 10 feet? If this is possible the more smaller and compact the better. Thank you.
