Good Points. They have a card that goes in your wallet, they also give you a sticker to apply to a frequently used cc, so you dont have to keep a card on file. There are flaws but with some fine tuning I think it can be beneficial. Its sorta like online shopping, but in a B&M. On a side note, I just bought a used car, and when I went to test drive it, the lady gave me her keys, and there were 32(!) different keychain card thingys on it( yes, I counted)! Only 1 key and clicker tho.
