How can applicants claim to be familiar with P.O.S. if every P.O.S. system is different?

Question

Someone who has not used a P.O.S. System for a while could easilly get a job in a venue if all P.O.S. systems are different and the venue would need to train the new employee is this correct?

Answer 1

The systems are different, but the basic underlying processes are the same. If you've had significant experience in how a POS system works, you will be able to learn the details of a newer system quickly. At least you'll know what a bar code is and what it does at the scanner.
