There are a few ways that one can pay for their meals at McDonald’s. You can either pay by cash, or depending on which country you are in, you can pay using a debit/credit card just by tapping the terminal. That being said, it seems that in the future you could possibly use your mobile phone to make your payments at the fast food outlet. This is according to an internal memo which shows that McDonald’s is getting ready to start training their staff on the new system, which will take advantage of NFC to facilitate these payments. The system is expected to roll out on the 15th of September which is why staff members are expected to be trained on it before then.
