(41~43) At some stores, people get stickers or stamps on a card when they spend money there. After they collect enough stickers or stamps, they can get gifts or buy things at low prices. Yesterday after I bought coffee; the clerk stamped on my cellphone. How cool it was! My first time! It looks like a stamp we used in the past, but there are many small dots at the bottom. You touch the screen of your cellphone to tell it what to do, and this is also the way smart stamps work. When people use a smart stamp, they hold the top part of the smart stamp. The small electrical charge from people's hands goes through it to the dots at the bottom. Then, the smart stamp tells your cellphone messages with them. The dots of different stores are in different patterns. no alla lil est sill lo busolos With smart stamps, stores don't have to make stickers or cards, and people don't have to keep those things.
