The CandyShell Card from Speck Products merges the company’s popular CandyShell iPhone accessory with a slot for holding your ID, credit cards, or other items.

The idea is you can slide in up to three cards, plus room for cash, into the iPhone 4 case. Usually we see these ideal for exercising or heading out to the bar where you may not want to carry around a wallet or purse.

The CandyShell Card is available now in NightDrive Grey, GrapeEscape Purple, and Moonsicle White. The case work for both the AT&T and Verizon iPhone 4, and it retails for $39.95.
