Sure, there are a couple downsides--the one-at-a-time service kiosk means that slow people clog the system, and they won't always have what you want--but as a Netflix gap-filler, RedBox is just about optimal.
So, I was sad to get this notice from RedBox in my email:
A few days ago redbox detected and removed an illegal credit card skimming device at one of our 7,400 locations. At the same time, redbox also discovered evidence of skimming attempts in two other locations. Skimming involves the placement of an illegal device above the credit/debit card reader on a vending machine, ATM, or in this case a redbox. These devices are used to illegally read or store personal credit card information....The company has put the warning online, along with pictures of legitimate barcode scanners compared to skimming devices. It's not linked from their main page, though, which I think is bad form. Potential users, and not just current users, need to know about the very small risk a DVD vending machine presents.
Although there is no evidence currently that these skimming attempts were successful, consumer security is a top priority for redbox. Reviewing transaction records, there is a possibility that up to 150 customers may have been affected. Although only a small percentage of the millions of customers who use redbox each month, redbox has notified the major credit card companies so that they can monitor the situation. The redbox team is also working with local authorities to investigate the incidents and ensure your security.
Update: RedBox did the right thing and added a link to their homepage.
