Limited experience here, but with recent credit card uses I did not have to "sign" or enter a PIN.
You just insert your card in the newer terminals...
For debit cards... GET RID OF THEM. They are a disaster waiting to happen. My daughter and several friends have had their bank accounts frozen when their cards were compromised. We discussed this in another thread...
I'm not sure what advantage this gives you versus just 'dipping' the chipped card
But for some reason I feel odd using a credit card at a supermarket for food.
Stopped for milk this morning at a Heritage. I was noticing that there was no one in the store these past few early mornings so it looked like a safe place to stop.
Opened the door with one finger, opened the cold case with one finger and carried the milk to the register and out the door with one finger.
Went outside and cut off my finger. Safe !
I don't want to minimize the gravity of the covid-19 stuation but I do need to share a recent experience. I was out on a bike ride and at the bottom of Apple Pie Hill someone named William White III has dug a well and started a business bottling and selling a magical elixir that wards off the virus. I bought a case and the nice gentlemen even gave me green stamps. Some of our readers may want to note that 40,000 green stamps will get you a rake and custom mixed paint. The business has special hours for those of us over 60 but I drank so much of the elixir I can't remember what they are. Everyone please be well.
