With Congress focusing a lot of attention on identity theft, sometimes it's important to note that individuals have some responsibility for protecting their personal information. That hit home this morning as I rode to work on the S2 bus on 16th Street. Right behind me, a young professional man was on his cell phone, and he was making a credit card purchase. During his one-sided conversation, I learned his Visa credit card number — he repeated it very slowly so listeners could be sure to get it -- the expiration date of his card, his name and the correct spelling, his phone number, his new address — that was repeated too — his zip code, his email address, and his place of employment (the World Bank). I also learned that he was charging an item for $280.17. No, I didn't get his mother's maiden name. Daniel — that was his first name (I won't give any other details) — seemed oblivious of the fact that he was on a crowded bus. I know I'm honest, but can't attest to the honesty of a large group of strangers on the bus. Betcha, â€˜though, Daniel will be really indignant when he gets unauthorized charges on his Visa account. He'll probably even push for more laws to protect him.
