Appellant Bostec Systems, Inc. challenges a summary judgment dismissing its breach of contract and promissory estoppel claims against Mastercard International, Inc. Bostec argues that a trialworthy factual dispute remains as to whether Mastercard promised to require its members to purchase a machine--capable of affixing tamper-evident, paper signature panels to credit cards--were Bostec to design and develop such a machine.   Following plenary review, Laura Thorn, Ltd. v. Alletzhauser, 71 F.3d 991, 993 n. 4 (1st Cir.1995), after careful consideration of Massachusetts law and the entire record as illuminated by the briefs and oral argument, we are persuaded that the district court correctly concluded, as a matter of law, that though Mastercard encouraged Bostec's developmental efforts, it made no express or implicit promise that could support either a contract claim or a promissory estoppel claim.1

Viewed in the light most favorable to Bostec, the evidence reveals that Mastercard broached its idea for the development of a signature panel machine to Bostec in March 1987, and monitored Bostec's progress before finally approving a Bostec paper signature panel prototype in December 1991.   Bostec concedes, however, that no enforceable promise was made prior to Mastercard's March 1990 letter, which confirmed its commitment to require Mastercard members to use a "new secure signature panel."   Instead, Bostec contends that it is the entire course of dealings between the parties that evinces a promise to require Mastercard members to use only the paper signature panel machine developed by Bostec at Mastercard's suggestion.


3
Neither the course of dealings between the parties nor the March 1990 letter generated a trialworthy claim that Mastercard made a "sufficiently definite" promise to require its members to use, or acquire, only a tamper-evident, paper signature panel on its credit cards.  See Simons v. American Dry Ginger Ale Co., 140 N.E.2d 649, 652 (Mass.1957);  supra note 1. In November 1988, Mastercard sent Bostec (and others) specifications, explicitly permitting signature panels to be made from paper, mylar, film, or other comparable material.   Mastercard informed Bostec in May 1989 that it would not grant a monopoly to any one equipment supplier.   Finally, the March 1990 letter--confirming Mastercard's commitment to a "new secure signature panel"--cannot support a reasonable inference that Mastercard promised to require its secure signature panels to be made from paper to the exclusion of all other materials, or to require its members to purchase Bostec's paper signature panel machine.   Absent evidence of a sufficiently definite promise, the Bostec claims fail as a matter of law.   See supra note 1.

Affirmed.
