Smart cards can be either contact or contactless smart card. Smart card can provide personal identification, authentication , data storage, and application processing. However, as most components that talk directly to the hardware in Android, the RIL consists of an open source part, and a proprietary library. In order to support communication with the UICC secure element, support for this needs to be added to both to rild and to the underlying proprietary library, which is of course up to hardware vendors.

Since public key cryptography is typically not needed for mobile network authentication or secure OTA (which is based on symmetric algorithms), SIM cards rarely support RSA or EC. A reasonably secure symmetric and hash algorithm should be enough to implement a simple password manager though, so in theory we should be able to use even a lower-end SIM.

The recent Bitcoin app problems traced to a repeatable PRNG in Android, controversy around the Dual_EC_DRBG PRNG algorithm, which is both believed to be weak by design and is used by default in popular crypto toolkits and finally the low-quality hardware RNG found in FIPS certified smart cards have highlighted the critical impact a flawed PRNG can have on any system that uses cryptography.

This allows to improve the security of Android apps by using the SIM as a secure element and both store sensitive data and implement critical functionality inside it. Commercial SIM do not allow for installing arbitrary user applications, but applets can be automatically loaded by the carrier using the SIM OTA mechanism and apps that take advantage of those applets can be distributed through regular channels, such as the Play Store.

Equipped with current—and even future—payment technologies promising universal retailer acceptance, incredibly intelligent security features, and the capacity to store all the information of up to twenty cards at a time (including not just credit and debit cards, but gift, loyalty, membership, and key cards as well), Plastic Card and its accompanying app, Plastic Wallet, are poised to fly by the competition.
