Putting the PayPal App To Work
It's not so much sending PayPal payments, since most everyone has a smartphone illuminating the inside of their trouser pockets these days, but the business's ability to receive that micro-transaction on the spot. It's not a difficult hurdle to straddle, of course, as it's solved either by the use of a "company" smartphone equipped with the PayPal app, or a laptop behind the counter.
Let's say you run a pub, and a tech-savvy beer hound has run out of cash. Do you let them leave early, or do you give them the option of buying one more pint using PayPal? Okay, so PayPal takes a small cut. The punter was heading out the door anyway, so keeping the meat on the seat a little while longer is worth the commission price.
Above the bar is a PayPal address or its associated smartphone number. The drinker fires up their PayPal app, enters the business's email address (and ideally adds it to their Contacts app, so next time they just select it from the address book) and adds the price of a pint of Scruttock's Old Dirigable. The bartender's smartphone app buzzes while the beer is still settling on the bar, and the transaction is complete.
Now apply this notion to a bunch of flowers, a sandwich, arts and crafts on a market stall, a haircut, a car wash or a full meal in a restaurant. Anyone can receive electronic payments, no matter how large or small.
