1) Caller-ID spoofing. It straight out should not be possible to spoof government phone numbers, 911, etc. My Android has "Scam Likely" show up when a scammer calls (I believe this is part of the STIR/SHAKEN protocol), this should be expedited, expanded, and improved upon.
2) Someone should not be able to buy $3000 of Target gift cards without doing a lot of explaining. Personal experience: The grocery store I go to; the registers will straight out refuse to ring up above $500 of gift cards, you have to use the Customer Service desk where their agents grill you (and I do mean grill you, their default mode seems to be "You're being scammed", especially if you're on the phone with someone).
3) If I buy gift cards in New York, there's zero reason someone in Bangalore, India should immediately be able to redeem those gift cards. Perhaps Target could should spend some of their data collection techniques on this instead of trying to figure out if your daughter is pregnant so they can send you maternity coupons.
4) Is there a reason unused gift cards bought within a certain amount of time shouldn't be refundable?
